In the shown pulley system, block B starts moving from rest to the right. At the shown instant, the weight W has moved up m with a variable velocity v(t) = 0.45 +0.5t m/s. (i) drive an equation for the relative position S/A (11) Determine the relative velocity between block A and B at the shown instant when the weight acceleration =1.1. Note at the shown isntant x =0.8, y = 1.4. W Answer:
