Answer 2

Given:

Force exerted on the body = 20 N

Displacement produced in the direction of force = 15 m

To find:

Work done by the person.

Solution:

We know that work done is the product of force and displacement produced in the direction of the force applied.

Work = Force*displacement

Work = 20*15 = 300J

Therefore the work done by the person is 300J.
