Problem

Two high performance bicycle wheels have the same mass but one is a solid disk and the other is a hoop with very light (as compared to the mass of the rim) spokes. Which wheel takes the most energy to accelerate to a speed vv? Ignore any air and rolling resistances. (a) The disk wheel requires more energy. (b) The spoked wheel requires more energy. (c) Both take the same amount of energy. (d) It depends on the radius of each wheel.
