(Figure 1)A roller coaster car may be approximated by a
block of mass m. The car, which starts from rest, is
released at a height h above the ground and slides along
a frictionless track. The car encounters a loop of radius R,
as shown. Assume that the initial height h is great enough
so that the car never loses contact with the track.
