A roller-coaster car of mass m = 750 kg starts from rest at the top of a hill 30 m
high, see Fig. 6.39. The roller-coaster travels a total distance of 250 m without
leaving the track and reaches a vertical height of only 25m on the second hill
before coming to a momentary stop. Find the thermal energy produced during
the free motion and estimate the average frictional force on the car.
