Question

A machine produced a 65 N force and moves a box 4.1 meters. This all happens in 5 seconds. How much power did the machine produce?

Answer 1

Power is the amount of work done over a period of time. The formula would then be:

P = W/t

However, work was not given in your problem but it can be easily solved with the given.

Work can be solved using the formula:

W= Fd
Where:
F = force
d = distance
W = work

So now let's solve for work:
Given:
F = 65N
d = 4.1m

W = Fd
= (65N)(4.1m)
= 266.5J

Now that we have work, we can solve for power:
Given: W = 266.5J
t = 5 s

P = W/t
= (266.5J)/(5s)
=53.30W

The machine produced 53.30W of power.
