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)   $2.65\times 10^{-3} \; W$
