1. The problem statement, all variables and given/known data An 0.80-kg cart rolls down a 30.0° hill from a vertical height of 0.50 m. The distance that the cart must roll to the bottom of the hill is 0.50 m/sin 30.0°=1.0 m. The surface of the hill exerts a frictional force of 5.0 N on the cart. Does the cart roll to the bottom of the hill? 2. Relevant equations I do know what equation to use or how to get the problem started. f=ma 3. The attempt at a solution F=9.8m/s^2(.8kg) F=7.84N(sin30) F=3.92N so it doesn't over come the frictional force.
