You push a friends sitting on a swing. If you push with 200N of force and your friend accelerates at a rate of 4 m/s^2. Find the mass of your friend.

e 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.

your answer is, orbit around the nucleus
