Given the force exerted by the child to pull the Wagon through the given distance and time, the average power delivered by the child is 16.9 Watts.

This question is incomplete, the complete question is:

A child pulls on a wagon with a force of 75N. If the wagon moves a total of 42m in 3.1min, what is the average power delivered by the child?

What is Power?

Power is simply the amount of energy transferred or converted per unit time.

It is expressed as;

P = W/t

Where W is work done and t is time elapsed.

But Work done is expressed as;

W = F × d

Where F is force applied and d is distance covered.

Hence;

Power = W/t = Fd / t

Given that;

Force exerted F = 75N = 75kgm/s²
Distance covered d = 42m
Time elapsed t = 3.1min = ( 3.1 × 60)s = 186s
Average power delivered P = ?

Power = Fd / t

Power = ( 75kgm/s² × 42m ) / 186s

Power = (3150kgm²/s²) / 186s

Power = 16.9 kgm²/s³

Power = 16.9 Watts

Given the force exerted by the child to pull the Wagon through the given distance and time, the average power delivered by the child is 16.9 Watts.
