1. Determinar cuanta fuerza es necesaria para empujar un móvil que se encuentra en reposo para que alcance una velocidad de 15 m/s en un tiempo de 20 segundos, considerando que dicho móvil tiene una masa de 1000Kg. No considere que existe fricción.
Responder:
Explicación:
Fuerza = Masa × aceleración
Dado que aceleración = velocidad final - velocidad inicial / tiempo
Fuerza = m (v-u) / t
Dado
Masa = 1000 kg
v = 15 m / s
u = 0 m / s
t = 20 segundos
Sustituye los valores dados en la fórmula para calcular la fuerza.
F = 1000 (15-0) / 20
F = 1000 (15) / 20
F = 15000/20
F = 750N
What is the resultant of 5N force pointing north and 7N force pointing south? Do not forget to include the direction.
Answer:
It would be 2N pointing South.
Explanation:
Since the forces are going in opposite directions, you can subtract them. Which makes it 7N south minus 5N North. That is 2N pointing South. Because the force going south is greater, it is the direction the force will be going.
what is an ammeter used for ?How can it be connected to make a measurement for a circuit component
Answer:
See the explanation below.
Explanation:
An ammeter is an instrument for measuring electrical currents in a circuit. To measure the current the ammeter must be connected in series with the circuit so that the current flows through it. At present time there are modern instruments such as the amperimetric clamp, which also serves to measure currents in a more easy way
Speed can be represented by many different ____________________ of distance and time.
Speed can be represented by many different units of distance and time.
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.
Speed is defined as distance per unit time so it's unit are meter per sec, kilo-meter per hour, that is different unit of distance and time.
Speed can be represented by many different units of distance and time.

How long will it take a person walking at 2.1 m/s to travel 13 m?
Answer:
I gonna give you the number so but you need to round 6.19047619048
Explanation:
This is a speed formula so you would use the formula speed=distance/timeYou need to rearrange it to time=distance/speedSo you need to divide 13m by 2.1 m/sA car has a velocity of 10m/s.it now accelerates for 1m/s for 1/4 minutes. Find the distance travelled in this time and final speed of the car
¡Hellow!
For this problem, lets recabe information:
v (Velocity) = 10 m/s
a (Aceleration) = 1 m/s²
t (Time) = 1/4 min = 25 s
d (Distance) = ?
v' (Final velocity) = ?
First, for calculate distance, lets applicate formula:
[tex]\boxed{\boxed{\text{d = Vo * t + (a * t}^{2})\text{ * 0,5} } }[/tex]
Lets replace according we information and let's resolve it:
d = 10 m/s * 25 s + (1 m/s² * (25 s)²) * 0,5
d = 250 m + (625 m) * 0,5
d = 2,5 m + 312,5 m
d = 314 meters.
Now, for calculate final speed, lets applicate formula:
[tex]\boxed{\boxed{\text{v' = v + a * t} } }[/tex]
Lets replace according we information and let's resolve it:
v' = 10 m/s + 1 m/s² * 25 s
v' = 10 m/s + 25 m/s
v' = 35 m/s
¿Good Luck?

Which of these warnings refers to a chemical property of the material?
Answer:
Please show the warning's
Explanation:
The warning refers to the chemical property of the material or object that is flammable.
What is Chemical Property?A chemical property is a feature that pertains to how a component, such as an ingredient or a compound, can alter as a result of a reaction. Due to bonding and other atomic structural characteristics, a substance develops these qualities as a result of its chemical identity.
Tactile or visual changes may occur in conjunction with chemical qualities. Chemical reactions commonly involve popping, fizzing, or the release of brilliant light. The emission of heat may also be a sign of a chemical reaction or chemical conversion that is taking place. Because the connections in the atomic structure are changing or breaking, these sensory clues appear.
Therefore, the warning refers to a chemical property of the material is flammable or combustible.

This waterbottle has a mass of .5 kg. If the net force acting on the bottle is five and to the right what is the bottles acceleration (hint: use formula a=f/m
Answer:
a = 10/s^2
Explanation:
Answer:
a=10 m/s *2 right
Explanation:
The net force (0.5 kg) divided by the mass (5 N) = 10
The force moved the object to the right.
So you Would put this in the equation a=___ m/s *2 _____
And you would get a=10m/s*2 right

when a light bulb is turned on electrical energy is transformed into two other types of energy. What are they and support your answer
Answer:
In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).

A falcon is diving at a speed of 30m/s. It accelerates at a rate of 40m/sand reaches a speed of
100m/s. Calculate the distance it travels during its acceleration.
Answer:
Reasd through the explanartion first :)
Explanation:
Initial velocity, u = 30 m/s
Final velocity, v = 100 m/s
Acceleration, a = 40 m/s²
Distance traveled, s = ?
According to the 3rd equation of motion,
We know that,
v² - u² = 2as
So, putting all the values, we get
⇒ v² - u² = 2as
⇒ (100)² - (30)² = 2 × 40 × s
⇒ 10000 - 900 = 80s
⇒ 9100 = 80s
⇒ 9100/80 = s
⇒ s = 113.75 m.
it takes 275n to set a stationary 77.3 crate in motion. what is the coefficient of static friction?
Note: I'm assuming the data 77.3 is the mass of the crate.
Answer:
[tex]\mu_s =0.36[/tex]
Explanation:
The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).
[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]
The normal force is numerical equivalent to the weight of the body if no other external forces are acting.
[tex]N=m\cdot g[/tex]
The mass of the crate is m=77.3 Kg, thus its weight and normal force is:
[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]
[tex]N= 757.54\ Nw[/tex]
Now we calculate the coefficient:
[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]
[tex]\boxed{\mu_s =0.36}[/tex]
Answer:
0.36
