Answer: Work done by the man will be 96 J.
Step-by-step explanation:
Work is defined as the amount of energy that is transferred in order to move an object by an external force. It is expressed in joules.
Mathematically,

Where,
W = Work done = ? J
F = Force applied = 48 N
d = Displacement of the body = 2 m
Putting values in above equation, we get:

Hence, work done by the man will be 96 J.
