Question

If the work done is 360 J, and the force used to do the work is applied over a distance of 12 m, what is the value of the force

Answer 1

Work done=force*distance
Force=work done/distance
=360/12
=30N

Answer 2

The formula for work is $W=Fdcos\theta$. Plugging in the numbers, you get: 
$360=F(12)cos(0)$
$F= \frac{360}{12}$
The answer is 30 N.
