An exercise machine indicates that you have worked off 2.5 Calories in a minute-and-a-half of running in place. What was your power output during this time? Give your answer in both watts and horsepower.
Step 1 of 3:
Our aim is to find the power output of the person in watts and horsepower.
The work done by the person W = 2.5 cal
The time duration t = 1.5 min = 90 s
1 cal = 4.186 J
1 hp = 746 J/s = 746 watt
