Answer:

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
