Would just be 860/420 which is ≈ 2W

Answer:

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.

[tex]P=\dfrac{W}{t}[/tex]

[tex]P=\dfrac{860\ J}{420\ s}[/tex]

P = 2.04 watts

or

P = 2 watts

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