Question

Blocks A and B are connected bt an inextensible cable, with this cable being wrapped around pulleys at A and E. Assume that the radii of these two pulleys are small compared with the other dimensions of the problem. Block A moves downward with a speed of vA Let vB be the speed of block B when sA > 0. SA Sa Problem 10: Which expression most accurately describes the speed of B as compared to the speed of A: c) UB=20A 0 (d) UB > 2uA O (e) More information is required to determine the relationship between the speeds of blocks A and B
