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

To find the power output of the horse, we can use the formula:

power = work / time

We are given that the horse does 860 J of work in 420 seconds. Substituting these values into the formula, we get:

power = 860 J / 420 s

Dividing 860 by 420, we get:

power = 2.047619...

Rounding this to the nearest whole number, we get:

power = 2 W

So the power output of the horse is 2 watts.
