You push a friend sitting on a swing. she has a mass of 50kg and accelerates at a rate of 4 m/s2. find the force you exerted

F=ma

f-x

m-50kg

a-4m/s^2

x=50kg*4m/s^2

x=200 Newtons

Mass of the friend sitting on the swing = 50 kg

Rate of acceleration = 4 m/s^2

The above information's are already given in the question. We need to utilize these information's in such a manner that the answer to the question can be determined easily.

We already know that

Force = Mass * acceleration.

This formula has to be used to find the force exerted.

Then

Force exerted = Mass of the friend * Acceleration

= (50 * 4) kg m/s^2

= 200 Newton

So the force exerted by me is 200 Newton. I hope the explanation and the procedure is clear to you and you are satisfied with it.
