The man pulls the boy up to the tree limb C by walking backward. If he starts from rest when xA = 0 and moves backward with constant acceleration aA, determine the speed of the boy at the instant yB = yB1. Neglect the size of the limb. When xA = 0, yB = h so that A and B are coincident, i.e., the rope is 2h long. Given:

a A = 0.2 m 2 S = 4 m h = 8 m
