Consider a bicycle wheel that initially is not rotating. A, block of mass m is attached to the wheel via a string and is allowed to fall a distance h. Assume that the wheel has a moment of inertia I about its rotation axis. Figure 1 of 2 > (a) IN Mass of block = m h Figure < 2 of 2 (b) Mass of block = M h Part A Consider the case that the string tied to the block is wrapped around the outside of the wheel, which has a radius TA as shown in (Figure 1). Find wą, the angular speed of the wheel after the block has fallen a distance h, for this case. Express WA in terms of m, g, h, ra, and I.
