The work done by weight lifter is 700 J.

W = F s

Here, W = work done,

F = force, given = 350 N

s = displacement, given = 2 m

Put these values in formula, W = Fs

W = 350 × 2

W = 700 J

Therefore, the work done by weight lifter is 700 J.

Work done includes both forces exerted on the body and the total displacement of the body. This block is preceded by a constant force F. The purpose of this force is to move the body a certain distance s in a straight path in the direction of the force.

The unit of work done is joule represented by J.
