Answer:
Work done, W = 18 J
Step-by-step explanation:
It is given that,
Force acting on the bag, F = 36 N
Distance covered by the bag, x = 0.5 m
We need to find the work done by the bag. The product of force and displacement covered is called the work done by the object. It is given by :

W = 18 J
So, the work done on the bag is 18 J. Hence, this is the required solution.
