The work done by the boy is 78 J.
The given parameters;
- force applied by the boy, F = 65 N
- distance traveled by the load, d = 1.2 m
The work done by the boy is the product of the applied force and the distance through the load is moved.
The work done by the boy is calculated as;
Work-done = Force x distance
Work-done =65 x 1.2
Work-done = 78 J.
Thus, the work done by the boy is 78 J.
