What is the average power developed by a motor
as it lifts a 400.-kilogram mass at constant speed
through a vertical distance of 10.0 meters in
(1) 320 W (3) 4,900 W
(2) 500 W (4) 32,000 W
P=Wd/t= Fd/t= mad/t
The Attempt at a Solution
How does the fact that acceleration is 0 change the way I should approach this question. The question says acceleration is constant.
On the other hand I tried using this formula.... P=Fv..... but because I dont know acceleration, I can't find 'F'.
