A horse moved a sleigh 1.00 kilometer by applying a horizontal 2000 newton force on its harness for 45.0 minutes. What is the power of the horse

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.
