A roller-coaster car shown in the figure is released from rest from a height h and then moves freely with negligible friction. The roller coaster track includes a circular loop of radius R in a vertical plane. Suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom in terms of R.
