In one movie scene, the hero lifts the 95 kg villain straight up through a vertical distance of 1.2 m in 0.52 s at constant speed. What power did he produce?

First you need to solve the energy required to lift that villain to a specific height. 

PE = mgh (Potential energy = mass x gravity x height)

PE = 95 kg x 9.8 m/s2 x 1.2 m
PE = 1117.2 Joules or newton-meter (J or N.m)

Then solve for power:

Power = Work/Time
Power = 1117.2 Joules/0.52 s
Power = 2148.46 Watts (W)
