Document Summary
Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. Partial credit will be given unless specified otherwise. Problem 1 (10 pts ): consider three identical wheel rims with the three configurations of spokes sketched below. For each wheel, the spokes have a uniform mass density and the same mass. The only difference is that the spokes are different in shape (as shown). If the three wheels roll simultaneously without slipping down an inclined plane from the same height, in what order will they reach the bottom of the inclined plane. Provide a sentence or two justifying your answer: a first, then b, then c, a first, then c, then b. B first, then c, then a: all three reach the bottom at the same time, consider the same physical situation where the inclined plane has a teflon surface which removes all friction between the wheels and the plane.
