frictionless roller coaster car of mass m = 951 kg tops the firsthill with speed v0 = 23.6 m/s at height h = 36.0 m. How much workdoes the gravitational force do on the car from that point to (a)point A, (b) point B, and (c) point C? If the gravitationalpotential 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?
