Determine power that motor must supply to the crate instant

Reference no: EM13972517

To use the principle of work and energy to determine characteristics of a mass being pulled up an incline and determine the power that must be supplied to the system when the efficiency of the input system is considered.

As shown, a 56kg crate is pulled up a s = 65? incline by a pulley and motor system. Initially at rest, the crate is pulleds = 4.5m up along the incline. Undergoing constant acceleration, the crate reaches a speed of 2.7m/s at the instant it has traveled this distance.

Part A - Power supplied to the crate when friction is considered

Considering the coefficient of kinetic friction, μ= 0.15, determine the power that the motor must supply to the crate the instant the crate travels a distance of 4.5m .

Express your answer to two significant figures and include the appropriate units.
