Learning Goal: As shown, a 59 kg crate is pulled up a = 60° incline by a pulley and motor system. Initially at rest, the crate is pulled s = 4.3 m up along the incline. Undergoing constant acceleration, the crate reaches a speed of 2.4 m/s at the instant it has traveled this distance.(Figure 1) Figure 1 of 1 > Part A - Power supplied to the crate when friction is considered Considering the coefficient of kinetic friction, A=0.15, determine the power that the motor must supply to the crate the instant the crate travels a distance of 4.3 m Express your answer to two significant figures and include the appropriate units. ▸ View Available Hint(s) P= Submit μÁ Value Submit P= Value A Provide Feedback Part B - Power supplied to the motor when efficiency is considered C If the motor has an efficiency of €=0.86, what power must be supplied to the motor to raise the crate?
