Work = (force) x (distance)
= (2,000 N) x (1,000 m)
= 2,000,000 joules
Power = (work done) / (time to do the work)
= (2,000,000 joules) / (45 minutes)
= ( 44,444 and 4/9) joules per minute
= 740.74 joules per second = 740.74 watts .
Note: This is almost exactly 1 "horsepower".
1 horsepower = 746 watts .
