Answer: 2.4 watts
Explanation:
Work done by horse = 910J
Time = 380 seconds
Power output of the horse = ?
Recall that power is the rate of doing work. Thus, power is workdone divided by time taken.
i.e Power = (work/time)
Power = 910J/380seconds
Power = 2.395 watts (rounded to two significant figures as 2.4 watts)
Thus, the power output of the horse is 2.4 watts
