Sketch a free body diagram, Apply the principle of work and energy to the system to find the tension in the rope. Please use solve with the method provided only and apply the relevant kinematic equation(s)

Keep final answer in lb*ft/s.

The crate, having a weight of 75 lb, is hoisted by the pulley system and motor M. If the crate
starts from rest and, by constant acceleration, attains a speed of 14 ft/s after rising 10 ft,
determine the power that must be supplied to the motor at the instant s =
10 ft. The motor has an
efficiency ɛ = 0.81.
