Question

A machine exerts a 100 N force to the right over a 5.00 meter length in 4.00 seconds. Calculate the power output of this machine.
_____ W


500.
125
80.0
0.200

Answer 1

Power = Δw/Δt
           or
Power = Δe/Δt

*in this case you are only given the force, distance and the time. I would solve for the work and then plug that value into the first power formula listed.

W = F * distance
w = 100 * 5
W = 500
so.......

Power = Δw/Δt
P = 500/4.00
P = 125 <-- that is the answer

hope this helps :)

Answer 2

500 but I could be wrong go with your gut my dude
