Question

To find power we need to determine?

Answer 1

Work and time needed to the work

Step-by-step explanation:

Power is defined as follows:

`P=(W)/(t)`

where

P is the power

W is the work done

t is the time needed to do the work

Since the work can also be rewritten as the product between force (F) and displacement (d):

W = F d

The power can be also rewritten as

`W=(Fd)/(t)`

But
`(d)/(t)` is equal to the velocity, v; so, power can be rewritten as product between force and velocity:

`P=Fv`
