Question

The sport of skateboarding provides an excellent example of the principle of Conservation of Energy. In particular, let us consider 'vert skateboarding' where a person rides the skateboard on a vertical ramp that forms part of a hemisphere referred to as a 'half-pipe.' It consists of the transition from the curved part to the flat and the vertical. Below is a schematic of a half-pipe with the 'vert'. The surface of the half-pipe and the material of the wheels on the skateboard allow for an almost frictionless ride. Therefore we will neglect friction in the following analysis.
