Quizplus · Accepted Answer

Power is the rate at which work is done. Work is the product of force and displacement. In this case, the force is the weight of the weightlifter, which is 265 kg, and the displacement is the height to which he lifts the weight, which is 2.20 m. The time taken to lift the weight is 2.10 s. Therefore, the power output is:Power = Work / Time = (Force x Displacement) / Time = (265 kg x 2.20 m) / 2.10 s = 2.72 kW
