Answer:
The work done is 120 J
Explanation:
Mechanical Work
Is the amount of energy transferred by a force. Like energy, it is a scalar quantity and its SI unit is the joule.
If F is the force and x is the distance, the mechanical work is:
W=F*x
The force is F=8 N and the body is displaced x=15 m.
Apply the above formula to calculate the mechanical work as follows:
W = 8 N * 15 m
W = 120 N.m
The unit Joule is N.m, thus
W = 120 J
The work done is 120 J
