Acar with an initial velocity of o m/s and a mass of 1500 kg reaches a velocity of 15 m/s in 5
seconds. what is the acceleration of the car? how much net force was required to reach
this acceleration?

The acceleration of the car is . And the force required to reach the acceleration is 4500 N.

Explanation:

Equations of Motion describe different relations between motion parameters. One of them is,

And, , from Newton’s laws

So, given,

Initial velocity of the car = 0  

Mass of the car, m = 1500 kg

Velocity acquired = 15 m/s

Time taken to acquire velocity t = 5 seconds.

Now, since  , To find the acceleration, rearrange the above equation, we get as follows,

Then, by applying the given data in above equation, we get

Now, find the force to reach acceleration as follows,
