Question

If i lift the 30kg object to a height of 2 meters in 0.5 seconds, how much power did I lift with?

Answer 1

Power = Work / time

Work = Force x distance

Force = mass x gravity

g = gravity = 9.8 m/s^2

m= mass = 30 kg

F = force = 30 kg x 9.8 m/S^2 = 294 N

Work = 294 N x 2 m = 588 J

Power = 588 J / 0.5 s = 11,600 W
