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.

Answer 1

the correct answer is 2w

Answer 2

By definition, the power is given by:

$P = \frac{W}{t}$

Where,

W: work done

t: time spent doing work

Therefore, substituting values we have:

$P = \frac{860}{420} P = 2.05 watts$

Rounding the nearest whole we have:

$P = 2 watts$

Answer:

The power output of the horse is:

$P = 2 watts$
