A student pushes a box with a force of 200 Newtons a distance of 10 meters. What is the work done? (Hint: A Newton-meter is equal to one joule.) If the student accomplished the task in the prior problem in 5 seconds, what was her power?

What will be an ideal response?


W 5 F 3 D 5 (200 N)(10 m) = 2,000 N m = 2,000 J
For power, W = 2,000 J/5 s = 400 J/s = 400 W (watts)
