Suppose a 225 kg motorcycle is heading toward a hill at a speed of 31 m/s. The two wheels weigh 12 kg each and are each annular rings with an inner radius of 0.280 m and an outer radius of 0.330 m. (a) How high can it coast up the hill, if you neglect friction in m? m= 195 kg v= 29 m/s h= 39 m
(b) How much energy is lost to friction if the motorcycle only gains an altitude of 39 m before coming to rest?
