1. The problem statement, all variables and given/known data a student wearing a frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 45N. How far must the student be pushed, starting from rest, so that her final kinetic energy is 352J? 2. Relevant equations 3. The attempt at a solution KE=1/2MV^2 352=1/2*(45/9.81)*V^2 Vf=12.39 and Vi=0 since it starts from rest Wnet=1/2MVf^2-1/2MVi^2 1/2*(45/9.81)*12.39^2=352.31 Wnet=FnetDCosX 352.31=45dcos0 d=7.83m I just wanted to know if that was a correct way of solving it or did i make a mistake somewhere? thx for the help.
