A 50 kg crate rests on a rough horizontal surface with µk=0.3. An electrically powered winch is utilize to accelerate the crate at a constant rate until it reaches a speed of v=5 m/s within a distance of s=20 m, If the motor has the efficiency of ε =70%, determine the power that must be supplied to the motor when s=20 m.
