Question

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.

Find the minimum initial height h at which the car can be released that still allows the car to stay in contact with the track at the top of the loop.
Express the minimum height in terms of R.
