The child is pulled up to the tree limb C by a man at A walking backward. The man starts from rest when xA = 0, and moves backward with a constant acceleration aA = 0.2 m/s 2 . Neglect the size of the tree limb. When xA = 0, yB = 8m so that A and B are coincident, i. e., the rope is 16 m long. What is the speed of the boy at the instant yB = 4m ?
