In an action-adventure movie, the hero lifts the 91-kg villain straight upward through a distance of 2.0 m in 0.54 s at a constant speed. What power does the hero produce while doing this?
-
P=W/t
W=F*d
F=m*g
therefore
P=m*g*d/t = 91*9.8*2/0.54 =~3303 [W]
W=F*d
F=m*g
therefore
P=m*g*d/t = 91*9.8*2/0.54 =~3303 [W]
