7-83. 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
