Question

The power required to exert 4-n force over 3 meters in 2 seconds is

Answer 1

6 W

Step-by-step explanation:

The work done by the force is equal to:

`W=Fd`

where

F = 4 N is the force exerted

d = 3 m is the displacement

Substituting,

`W=(4 N)(3 m)=12 J`

The power is equal to the ratio between work done and time taken:

`P=(W)/(t)`

where

W = 12 J is the work done

t = 2 s is the time

Substituting,

`P=(12 J)/(2 s)=6 W`
