A 2 kg mass moving along a horizontal surface at 10 m/s is acted upon by a 5 N force of
friction. Calculate the net force?

A 2 Kg Mass Moving Along A Horizontal Surface At 10 M/s Is Acted Upon By A 5 N Force Offriction. Calculate

Answers

Answer 1

Answer:

F = 20.61 N

Explanation:

Given that,

Mass of the object, m = 2 kg

It is moving with a speed of 10 m/s

It is acted upon by a 5 N of friction.

The force of gravity acts in downward direction which is given by :

W = mg

W = 2 × 10 = 20 N

5 N of force is acting in horizonal surface.

The net force is given by the resultant of two vectors as follows :

[tex]F=\sqrt{20^2+5^2} \\\\=20.61\ N[/tex]

So, the net force acting on the object is 20.61 N.

Answer 2

The net force acting on the mass is equal to 13.6 Newton.

Given the following data:

Mass = 2 kgSpeed = 10 m/sForce of friction = 5 N

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 [tex]m/s^2[/tex].

To calculate the net force:

First of all, we would determine the normal force acting on the mass.

Mathematically, the normal force is given by the formula:

[tex]F_N = mg[/tex]

Where:

m is the mass of an object. g is the acceleration due to gravity.

Substituting the given parameters into the formula, we have;

[tex]F_N = 2 \times 9.8[/tex]

Normal force = 19.6 Newton

To find net force:

[tex]Net\;force = 19.6 - 5[/tex]

Net force = 13.6 Newton.

Note: We subtracted because friction opposes the motion of an object and as such acts in opposite direction.

A 0.111 kg hockey puck moving at 55 m/s is caught by a 80 kg goalie at rest. With what speed does the goalie slide on the (frictionless) ice? a 3.78 m/s b 2 m/s C 0.076 m/s d 1.056 m/s​

Answers

Answer: 0.076 m/s

Explanation:

Momentum is conserved:

m v = (m + M) V

(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V

V = 0.076 m/s

After catching the puck, the goalie slides at 0.076 m/s.

A 0.111 kg hockey puck moving at 55 m/s is caught by a 80 kg goalie at rest. With speed does the goalie slide on the ice is 0.076 m/s

What is speed?

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Momentum is conserved:

m v = (m + M) V

(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V

V = 0.076 m/s

After catching the puck, the goalie slides at 0.076 m/s.

What distance did it travel during the next 25 s? c. What total distance did it travel? d. What was its average speed during the first 45 s? e. What was its average speed during the next 25 s? f. What was its average speed for the entire trip? g. What was its displacement during the first 45 s? h. What was its displacement during the next 25 s? i. What was its total displacement?

Answers

Answer:

Explanation:

Given

1 ) 140 m west in 45 s .

2 ) 90 m east in 25 s .

a )

distance travelled in first 45 s = 140 m

b ) distance travelled in next 25 s = 90 m

c ) Total distance travelled = 140 m + 90 m

= 230 m

d ) average speed in first 45 s

= distance in 45 s  45

= 140 / 45 = 3.11 m /s

e ) average speed in next 25 s

distance in 25 s / 25

= 90 / 25 = 3.6 m /s

f ) average in entire trip

=  total distance / total time

= (140 + 90) / ( 25 + 45 )

= 3.28 m /s

g )

displacement in first 45 s = 140 m towards west

h )

displacement in next 25 s = 90 m towards east

i )

total displacement = 140 - 90

= 50 m towards west .

A student collects 25 mL of gas at 96 kPa. What volume would this gas occupy at 101.325 kPa. There is no change in temperature or mass.

Answers

Answer:

The answer is 23.69 mL

Explanation:

The new volume can be found by using the formula

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

From the question we have

101.325 kPa = 101325 Pa

96 kPa = 96000 Pa

From the question we have

[tex]V_2 = \frac{25 \times 96000}{101325} = \frac{2400000}{101325} \\ = 23.68615840...[/tex]

We have the final answer as

what did taking measurements reveal about the velocity of the fireball? Was the fireball’s velocity constant or changing?

Answers

Answer:

The fireball slows down when moving upward. It speeds up when moving downward. So, its velocity is always changing.

Answer:

The fireball went in the air and slowed down. This is because, the gravity holds us down on earth and if not, we would be floating everywhere. So, the fireball slows down because the gravity is pulling it back down. As well as it's going down, it becomes faster. Just like when we jump, we come down pretty fast. So, when the gravity pulls you down and you go down it starts to pick up speed. Thats just how gravity works.

A permanent magnet picks up an iron nail, magnetizing the nail. How is this system different from an electromagnet?

Answers

Answer:the nail is magnetized by a permanent magnet instead of by a solenoid with an electric current running through it

Explanation:

The permanent magnet magnetizing the nail will differently function like electromagnet, by utilizing the electric current through the iron. Hence, option (B) is correct.

The given problem is based on the concept and fundamentals of magnetization. The term magnetizations means that the density of magnetic dipole moments induced in a magnetic material, when it is placed near a permanent magnet.

In the given problem, the magnetization of iron nail takes place by passing the current through the nail.The electric current utilize the electric charge which responds the electric field. When the current carrying nail is placed beside the permanent magnet, the dipole set up and it will create a polarity for which the nail will now itself behave as a magnet.

Thus, we can conclude that the permanent magnet magnetizing the nail will differently function like electromagnet, by utilizing the electric current through the iron. Hence, option (B) is correct.

A car has a velocity of 24 m/s. Two seconds later it reaches the bottom of the hill with a velocity of 45 m/s. What is the acceleration of the coaster?

Answers

Answer:

a = 10.5 m/s²

Explanation:

In order to find the acceleration of the car we will use the basic definition of the acceleration, that is the rate of change of velocity. So, the definition of the acceleration of the car will be:

a = (Vf - Vi)/t

where,

a = acceleration = ?

Vf = Final Velocity = 45 m/s

Vi = Initial Velocity = 24 m/s

t = time = 2 s

Therefore,

a = (45 m/s - 24 m/s)/2 s

a = 10.5 m/s²

Bird man is flying horizontally at a speed of 30m/a and a height of 69 m. Bird man releases a turd directly above the start of the field. How far from the start of the field should the robot hood the bucket to catch the turd?

Answers

Answer:

The distance is [tex]d = 112.5 \ m[/tex]      

Explanation:

From the question we are told that

   The horizontal speed is  [tex]v_x = 30 \ m/s[/tex]

    The height is [tex]s = 69 \ m[/tex]

     

Generally from kinematic equation we have that

    [tex]s = ut + \frac{1}{2} gt^2[/tex]

Here u  is the initial velocity of the turd in the vertical direction and the value is 0 m/s

So

    [tex]69 = 0 * t + \frac{1}{2} * 9.8 t^2[/tex]

=>   [tex]t = \sqrt{\frac{2 * 69}{4.9} }[/tex]

=>   [tex]t = 3.75 \ s[/tex]

Generally the distance which the robot have to  hood the bucket in order to catch the turd  is mathematically represented as

     [tex]d = v_x * t[/tex]

=>  [tex]d = 30 * 3.75[/tex]

=>  [tex]d = 112.5 \ m[/tex]

Answer:

Explanation:

Given that,

A stunt man climb up 29.4 meters into a cannon. He gets fired horizontally out of the cannon with a speed of 57.1 m/s.

We need to find the time for which was the stunt man in the air. Let it is t. It can be calculated using second equation of motion as follows :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

u is initial speed and it is 0

[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 29.4}{9.8}} \\\\t=2.44\ s[/tex]

So, the stunt man is in the air for 2.44 seconds.
