Problem 7-83 Power - Part 2 - B

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. $1.84\; m/s$]

No. Power is the time-rate of using energy.
