I don't understand how to approach this question, I'm lost in where energy gets involved. Any help would be appreciated
A 110kg person is traveling at 3 m/s on a frictionless surface toward a wall, then stops themselves by pushing against the wall. During the push, the person's center of mass moves 0.3 m toward the wall. What is the change of the person's kinetic energy, and what is the average force exerted on the wall?
