QUESTION 9
Tony Hawk is skating through a half-pipe with a radius of 4 m.Initially he is in a crouched position with his center of mass 0.5m above the surface of the half-pipe. He starts from rest with hiscenter of mass a height of 3 m above the base of the half-pipe andexperiences no loss of energy from friction as he moves. At thebottom of the half-pipe he stands up and lifts his arms into theair, thereby raising his center of mass to 1.0 m. He then continuesup the other side of the half-pipe. What is the maximum height (inm) that his center of mass reaches on the other side of thehalf-pipe? You may model Tony as a point particle.
