What will be th acceleration of recoil when a 60-kg person on rollerskates pushes against a wall with a force of 30 N?

Question

agent0smith · Answer

The reaction force of the wall on the person is the same: 30N

use F = ma

you know the mass of the person, and the force

anonymous · Answer

isn't the equation Fnet=ma
So wouldn't you have to find the net force first, then use that equation?
