How much friction do on skateboarder as herides to bottom

Reference no: EM13555212

A 72.5 - kg skateboarder stands at the edge of a half pipewith a diameter of 5.46 m . he gently tips over the edge and ridesto the bottom where his speed is 6.94 m/s. he then kicks toincrease his speed to 8.53m/s as he starts to ride up the otherside of the half pipe.

A} - How much work does friction do on the skateboarder as herides to the bottom?
B} - Assuming friction does the same amount of work as in {A}on the skateboarder as he rides up the other side of the half pipe,how high above the edge does he reach?
C} - If the half pipe was frictionless and the skateboarderdid not kick at the bottom, what quantity(be specific) is conservedas the skateboarder rides from one edge to the other?
