A ball of 1lb is sliding around in a circular path with a speed as shown. If the attached wire is pulled down through the hole with a constant speed of 1.5ft/s, 1) determine the ball's speed at the instant when r=1.5ft; 2) the work done by the wire; 3) time required for the ball to get there. Neglect friction and the size of the ball. 11b B=3 ft (VB)₁ = 6 ft/s v,=1.5ft/s
