Answer:

Work done, W = -60 N

Explanation:

It is given that,

Friction force applied as you slide a heavy box, F = -60 N

Distance, d = 2 m

We have to find the work done by the frictional force. Frictional force is an opposing force. The work done is given by :

W = Force × distance

[tex]W=-30\ N\times 2\ m=-60\ J[/tex]

Hence, the work done by the frictional force is -60 joules.
