Answer: The work done by F_{2} is 25 J.

Explanation:

Given that,

Mass = 2 kg

Force F_{1}= 20 N

ForceF_{2}= 5N

We know that,

The work done is the product of the force and distance moves in the direction of the force.

W = Fd

The work done by second force

W = F_{2}d

W = 5\times5

W = 25 J

Hence, the work done by F_{2} is 25 J.
