Consider two bicycle riders, a and b. the two riders have equal masses mrider a = mrider b and their respective bicycles also have similar frames, mframe a = mframe b . finally, the wheels of the two bicycles have equal masses mwheel a = mwheel b and equal radii r wheel a = r wheel b but different mass distributions: the wheels of bike a have most of their masses at the rims, wheel a, while the wheels of bike b have their masses ‘spread’ evenly over the whole wheel area, wheel b. the two cyclists travel at the same speed on level ground. they approach a low hill and decide to coast up instead of hard pedalling. at the top of the hill, which of the two bikes will have a larger speed? assume no friction nor air resistance, and all the wheels roll on the ground without slipping.
