Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving
upwards and is slowing down at a rate of 2.0 m/s? What is Abdul's apparent weight?
Use g = 10 m/s

Answers

Answer:

Abdul has an apparent weight of 600 newtons.

Explanation:

The statement is incorrectly written. Its correct form is:

Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving upwards and is slowing down at a rate of 2.0 m/s2. What is Abdul's apparent weight? Use g = 10 m/s2.

According to the statement, we know that elevator and Abdul himself are moving upwards and decelerating, which means that Abdul feels a force from elevator is the same direction of his weight. From 2nd Newton's Law we find the following equation of equilibrium:

[tex]\Sigma F = F-m\cdot g = m\cdot a[/tex] (1)

Where:

[tex]F[/tex] - Apparent weight, measured in newtons.

[tex]m[/tex] - Mass of Abdul, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]a[/tex] - Net acceleration of the elevator-Abdul system, measured in meters per square second.

In (1) we clear the apparent weight:

[tex]F = m \cdot (a+g)[/tex]

If we know that [tex]m = 50\,kg[/tex], [tex]a = 2\,\frac{m}{s^{2}}[/tex] and [tex]g = 10\,\frac{m}{s^{2}}[/tex], we find that the apparent weight of Abdul is:

[tex]F = (50\,kg)\cdot \left(2\,\frac{m}{s^{2}}+10\,\frac{m}{s^{2}} \right)[/tex]

[tex]F = 600\,N[/tex]

Abdul has an apparent weight of 600 newtons.

What is the speed in meters per second of a car that is travelling at 82km/h?

Answers

Divide by 3.6
82/3.6 = 22.8 m/s

Answer:

22.777777777777 m/s

Explanation:

Since 1 kilometer is 1000 meters, then 82 km is 82000 meters. Since one hour is the same as 3600 seconds, then the answer is pretty simple: 82000/3600 or 820/36. That gets you 22.77777 or 22.78. Hope this helps

1. Some penguins are playing turtle hockey on the frictionless ice. Ramona the penguin hits the turtle

with a force of magnitude F, and the turtle experiences an acceleration of magnitude a (Fand a are of

unknown size). Francisco the penguin hits the same turtle with a force of magnitude three times

greater than Ramona's force (3F). What will the resulting acceleration of the turtle be? Answer in

terms of a. Support your answer with reasoning and reference to Newton's Second Law.

Answers

Answer:

a' = 3a

Explanation:

Newton's Second Law gives the magnitude of the unbalanced force applied to an object as follows:

F = ma

where,

F = Force Applied

m = Mass of Object

a = acceleration

FOR RAMONA'S PUSH:

F = F

m = m

a = a

Therefore,

F = ma  

a = F/m   ---------------- equation (1)

FOR FRANSICO'S PUSH:

F = 3F

m = m  (mass of turtle will be same)

a = a'

Therefore,

3F = ma'  

a' = 3F/m

using equation 1

a' = 3a

Disponemos de datos de presión y volumen de tres situaciones de un gas ideal que se han medido manteniendo la temperatura del gas constante representa los valores de un gráfico p-v expresa matemáticamente la ley de Boyle-Mariotte y calcula el valor de la constante

Answers

Answer:

Explanation:

This is an exercise in thermodynamics, the ideal gas equation is

          PV = n R T

In this case the temperature is constant, so

         n R T = cte

throughout the experiment

           

We can write the relationship for the three points 1, 2 and 3

         P₁ V₁ = P₂ V₂ = P₃ V₃ = cte

In the attached graph we can see a graph of this relationship

the data for this graph are

 V(m³)     P ( Pa)

  V₀          P₀

  V₀/2    2 P₀

  V₀/4    4 P₀

for the graph, let it be assumed that V₀ = 1 and P₀ = 1

 

To calculate the value of the constant s, you must know the moles of gas and the temperature at which the experiment is carried out, for example, if we have a mole of gas and room temperature (T = 300K), the constant is

       n R T = 1   8,314  300

       n R T = 2492.2 J

Answers

A cannonball is shot from the top of a 47.8 m high hill at a speed of 53.7 m/s. The height then is 61.81 m/s.

What are kinematic equations?

The motion of an object with constant acceleration is described by a set of equations known as kinematic equations. Integrals, derivatives, and rates of change must all be understood in order to solve kinematics equations.

Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value.

The kinematic equation is:

v² = u² + 2gs (a = g)

Where u is the initial velocity, a is the acceleration, and v is the velocity after the time period t.

(53.7)² + 2 x 9.8 x 47.8 m

Therefore, the height is 61.81 m/s.

You throw a ball straight down off the roof of a 47 m tall building with an initial velocity of -8m/s.

When does the ball hit the ground?

Answers

Answer:

t = 2.38 [s]

Explanation:

To solve this problem we must use the following equation of kinematics. We must clarify that both the acceleration and the initial velocity were taken as positive, since the velocity of the movement coincides with the direction of the acceleration.

[tex]x =x_{o} +v_{o} *t+(\frac{1}{2} )*a*t^{2}[/tex]

where:

x - Xo = distance = 47 [m]

Vo = initial velocity = 8 [m/s]

a = gravity acceleration = 9.81 [m/s²]

t = time [s]

Now replacing these values in the equation:

47 = 8*t + 0.5*9.81*t²

47 = 8t + 4.905t²

47 = 4.905*t(1.63 + t)

9.58 = t*(1.63 + t) solving this equation (cuadratic)

we found that t = 2.38 [s]

accelerates from rest to a speed of 4 m/s in 16 s. What is the mass of the box?

Answers

Answer:

[tex]m = 44~Kg[/tex]

Explanation:

Net Force

Newton's second law explains the dynamics principles when a number of forces are applied to an object.

The net force vector is the sum of the individual vector forces applied. The magnitude of the net force is related to the magnitude of the acceleration of the body as follows:

[tex]Fn=m.a[/tex]

Furthermore, the acceleration can be calculated if we know the kinematic behavior of the body:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

Where vf, vo, and t are the final speed, initial speed, and time, respectively.

The box is pushed across the floor with a force of 25 N against a frictional force of 14 N.

The net force applied to the box is:

[tex]Fn = 25 N - 14 N = 11 N[/tex]

We also know the box is accelerated from rest (vo=0) to vf=4 m/s in t=16 seconds, thus:

[tex]\displaystyle a=\frac{4-0}{16}[/tex]

[tex]a = 0.25~m/s^2[/tex]

From the equation:

[tex]Fn=m.a[/tex]

We solve for m:

[tex]\displaystyle m=\frac{Fn}{a}=\frac{11~N}{0.25~m/s^2}[/tex]

[tex]\mathbf{m = 44~Kg}[/tex]

if a large bust and small cardboard going the same speed which vehicle has more kinetic energy​

Answers

Answer:

  bust

Explanation:

At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.

Answer:

Bust

Explanation:

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

A 200 g blob of clay moves with a speed of 10 m/s towards a 300 g cart that is initially at rest.

a. What is the momentum of the system before the blob of clay strikes the cart?

b. What must be the momentum of the system after they come together?

c. If the blob of clay sticks to the cart, with what speed will the clay and cart move after they come together?

Answers

Answer:

a. 2 kg*m/s

b. [tex]p_{T_{f}} = 0.5v_{f} = 2 kg*m/s[/tex]

c. 4 m/s

Explanation:

a. The momentum of the system ([tex]p_{Ti}[/tex]) before the blob of clay strikes the cart is:

[tex] p_{Ti} = p_{b} + p_{c} [/tex]

Where:

[tex]p_{b}[/tex] is the momentum of the blob clay

[tex]p_{c}[/tex] is the momentum of the car      

[tex] p_{Ti} = m_{b}v_{b} + m_{c}v_{c} [/tex]

Since the car is initially at rest, [tex]v_{c}[/tex] = 0

[tex] p_{Ti} = 200 g*\frac{1 kg}{1000 g}*10 m/s + 0 = 2 kg*m/s [/tex]

b. The momentum of the system after they come together:

[tex]p_{T_{f}} = m_{b}v_{b} + m_{c}v_{c}[/tex]

Since they come together, [tex]v_{b}[/tex] =

[tex]p_{T_{f}} = v_{f}(m_{b} + m_{c}) = v_{f}(0.2 kg + 0.3 kg) = 0.5v_{f}[/tex]   (1)

Because we do not have the final speed we can not calculate the final momentum.

                   

c. We can find the speed of the clay and car by conservation of the momentum:

[tex] p_{i} = p_{f} [/tex]

The initial momentum of the system was founded in part "a" (p = 2 kg*m/s), so we have:

[tex] 2 kg*m/s = m_{b}v_{b_{f}} + m_{c}v_{c_{f}} [/tex]

Again, when they come together, the final speed is the same:

[tex] 2 kg*m/s = v_{f}(m_{b} + m_{c}) [/tex]                

[tex] v_{f} = \frac{2 kg*m/s}{0.2 kg + 0.3 kg} = 4 m/s [/tex]

Now, since we found the final speed we can calculate the momentum of the system after they come together (equation 1):        

[tex] p_{T} = 0.5v_{f} = 0.5 kg*4m/s = 2 kg*m/s [/tex]
