Problem 49GP
A 55 kg skateboarder wants to just make it to the upper edge of a “half-pipe” with a radius of 3.0 m, as shown in Figure P10.55. What speed does he need at the bottom if he is to coast all the way up?
a. First do the calculation treating the skateboarder and board as a point particle, with the entire mass nearly in contact with the half-pipe.
b. More realistically, the mass of the skateboarder in a deep crouch might be thought of as concentrated 0.75 m from the half-pipe. Assuming he remains in that position all the way up, what is needed to reach the upper edge?
