Aweightlifter lifts a set of weights a vertical distance of 2 meters. if a constant net force of 350 n is exerted on the weights, what is the amount of work done on the weights? :
350n multiplied by 2m = 700

**if the weightlifter in the previous question takes a total of 2 seconds to life the weights, how much power is performed

The work done by the weightlifter, W = 700 J

The power of the weightlifter, P = 350 watts

Explanation:

A weightlifter lifts a set of weights a vertical distance, s = 2 m

The force exerted to lift the weight, F = 350 N

The work done by the body is defined as the product of the force applied by the body to the displacement it caused.

                            W = F x s

                                = 350 N x 2 m

                                = 700 J

The work done by the weightlifter, W = 700 J

The time taken by the weightlifter to lift the weight, t = 2 s

The power is defined as the rate of body to do work. It is given by the equation,

                            P = W / t

                               = 700 J / 2 s

                               = 350 watts

Hence, the power of the weightlifter, P = 350 watts
