Answer:

The correct answer is 0.0 J.

Explanation:

Force exerted o the trunk by man ,F= 250 Newtons

Displacement of the trunk,s = 0 m

Work done is defined as product of force applied on the body and displacement of the body due to applied force.

Work done = Force × Displacement

[tex]W.D =250 N\times 0 m =0 J[/tex]

Hence, the correct answer is 0.0 J.
