The crate A of weight W=27lb is being pulled to the right by the winch at B. The crate starts at x=0 and is pulled a total distance 15ft over the rough surface for which the coefficient of kinetic friction is 0.3. The force P in the cable due to the winch is 66.4758 lb/ft. Using work-energy principle, determine the speed of the block when?
