15-111. A box having a weight of 8 lb is moving around ina circle of radius rA=2 ft with a speed of (vA)1=5 ft/s whileconnected to the end of a rope. If the rope is pulled inwardwith a constant speed of v, =4 ft/s, determine the speed ofthe box at the instant rg = 1 ft. How much work is doneafter pulling in the rope from A to B? Neglect friction andthe size of the box.Tg = 1 ftA = 2 ffv, = 4 ft/s(vA)1 = 5 ft/s

Given data rA=2 ftvA1=5 ft/secvr=4 ft/srB=1 ft
