What is its gravitational potential energy relative to the bottom of the hill?
B. If the car rolls down the hill (with the engine off) with negligible friction and air resistance, what will its kinetic energy be when it reaches the bottom?
C. Suppose instead that the amount of work done on the car by the frictional and air resistance forces as the car rolls down the hill is 50,000 Joules. What then is the kinetic energy of the car when it reaches the bottom of the hill?
