Problem 15.111
A box having a weight of 4 lb is moving around in a circle of radius rA = 2 ft with a speed of (vA)1 = 5 ft/s while connected to the end of a rope. The rope is pulled inward with a constant speed of vr = 4 ft/s. Neglect friction and the size of the box. I JUST NEED HELP SOLVING FOR B
A: Determine the speed of the box at the instant rB = 1 ft. (ANSWER = 10.8 ft/s)
B: How much work is done after pulling in the rope from A to B?
