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]
Correct!
P = 2.65X103
W
The relationship between
Power and Energy is:
(A)
P
= E/t
(C)
E
= P/t
