Question

As you slide a heavy box across the floor, friction applies a force of -30 n over a distance of 2 m. how much work is done by friction?

Answer 1

you have -60 joules of work that is done because work is force x distance

Answer 2

Work done, W = -60 N

Step-by-step 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

`W=-30\ N* 2\ m=-60\ J`

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