Question

A horse does 860 J of work in 420 seconds while pulling a wagon. What is the power output of the horse? Round your answer to the nearest whole number.

The power output of the horse is
W.

Answer 1

Would just be 860/420 which is ≈ 2W

Answer 2

Power output, P = 2 watts

Explanation:

It is given that,

Work done by a horse, W = 860 J

Time taken, t = 420 seconds

We need to find the power output of the horse. Power output is given by work done divided by total time taken i.e.

`P=(W)/(t)`

`P=(860\ J)/(420\ s)`

P = 2.04 watts

or

P = 2 watts

So, the power output of the horse is 2 watts. Hence, this is the required solution.
