Answer:
B) 6 W
Explanation:
First of all, we need to find the work done by the force. This is given by
[tex]W=Fd[/tex]
where
F = 4 N is the magnitude of the force
d = 3 m is the distance through which the force is applied
Substituting,
[tex]W=Fd=(4 N)(3 m)=12 J[/tex]
Now we can find the power, which is given by
[tex]P=\frac{W}{t}[/tex]
where
W = 12 J is the work done by the force
t = 2 s is the time taken
Substituting,
[tex]P=\frac{12 J}{2 s}=6 W[/tex]
