If a powerlifter raises a 1000 n weight a distance of 2.0 meters in 0.5 seconds, what is his power output?

4000 W

Explanation:

Power output is equal to the amount of work done per unit time.

Work done = Force × displacement

Here, work done = (mg) h ( gravitational potential energy)

W = (1000 N)(2.0 m) = 2000 J

Thus, power output = W/t = (2000 J) ÷ (0.5 s) =4000 J/s = 4000 W

When a power-lifter raises a 1000 N weight a distance of 2.0 m in 0.5 s, his power output is 4000 W.
