Aradio-controlled car increases its kinetic energy from 3 j to 10 j over a distance of 1 m. what was the average net force on the car during this interval?

Net force, F = 7 N

Explanation:

It is given that,

Initial kinetic energy of the car,

Final kinetic energy of the car,

Distance, d = 1 m

We need to find the average net force on the car during this interval. It is given by using the work energy theorem as :

Also, W = F.d    d = distance and F = net force

F = 7 Newton

So, the average net force on the car during this interval is 7 newton. Hence, this is the required solution.
