Question

A horse does 910 J of work in 380 seconds while pulling a wagon. What is the power output of the horse? Round your answer to two significant figures.

Answer 1

Answer:2.4w

Step-by-step explanation:

Answer 2

Answer: 2.4 watts

Step-by-step 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
