The horse's power is 750 W
From the question,
We are to determine the horse's power
Power is the rate at which work is done
∴ The horse's power can be determine by using the formula
\(Power = \frac{Work}{Time}\)
From the question
Work = 15000 J
Time = 20 s
Putting the parameters into the formula
\(Power = \frac{Work}{Time}\)
We get
\(Power= \frac{15000}{20}\)
∴ Power = 750 W
Hence, the horse's power is 750 W
