They do the same amount of work, but Wanda operates at a higher power level.

Work

Work is the amount of energy needed to move an object a particular distance.  Power is the work done per unit of time.

Let acceleration due to gravity (g) = 10 m/s²

For Wanda:

Work = mass * g * height = 60 kg * 10 m/s² * 1 m = 600 J

Power = work / time = 600 J / 3 s = 200 J/s

For Vision:

Work = mass * g * height = (60 * 1 kg) * 10 m/s² * 1 m = 600 J

Power = work / time = 600 J / 120 s = 5 J/s

They do the same amount of work, but Wanda operates at a higher power level.
