2. A skateboarder with his board can be modeled as a particle of mass 76.0 kg, located at his center of mass 0.500 m above the ground. As shown in figure, the skateboarder starts from rest in a crouching position at one lip of a cylinder of radius 6.80 m with its axis horizontal. On his descent, the skateboarder moves without friction and maintains his crouch so that his center of mass moves through one quarter of a circle. Find his speed at the bottom of the half-pipe (point B). Answer: VB 11.22 m/s Solution
