In the figure, a frictionless roller coaster car of mass m = 818 kg tops the first hill with speed v 16.8 m/s at height h 37.6 m. How much work does the gravitational force do on the car from that point to (a) point A, (b) point B, and (c) point C? If the gravitational potential energy of the car-Earth system is taken to be zero at C, what is its value when the car is at (d) B and (e) A?
