Part A The crate, having a weight of 58 lb, is hoisted by the pulley system and motor M. The crate starts from rest and, by constant acceleration, attains a speed of 12 ft/s after rising 10 ft. The motor has an efficiency e = 0.61. (Figure 1) Determine the power that must be supplied to the motor at the instant s = 10 ft. Express your answer in horsepowers using three significant figures.
