Question

A 55 kg skateboarder with the board) wants to just make it to the upper edge of a 'half-pipe" with a radius of 3.0 as shown in the figure_ The thickness of the pipe can be assumed to be negligible_ 3.0 m What speed V; does he need at the bottom if he is to coast all the way Qp we treat the skateboarder with the board as a point particle, with the entire mass nearly in contact with the half-pipe? (TI) if the mass of the skateboarder with the board was in a deep crouch and can be thought of as concentrated 0.75 from the half-pipe, and assume he remains in that position all the way Up to reach the upper edge?
