Problem 7-83 Power

A \(2.65-kW\) motor is used to lift crates vertically upward in a factory. What is the maximum speed at which a crate of mass \(147\; kg\) can be lifted by this motor? Assume that all the motor's power goes into lifting. (Hint: determine the height that the crate can be lifted in \(1.00\; s\).) [Ans. \(1.84\; m/s\)]

The power of the motor in watts (\(W\)) is:
(A)   \(2.65\; W\)

(B)   \(2.65\times10^3\; W\)

(C)   \(2.65\times 10^{-3} \; W\)
