Question

What amount of work is done on a chair that is pushed 9 m across a floor b y a horizontal 30-N net force?

Answer 1

`W = 270n*m`

Explanation:

Assuming there is no friction the equation for Work is Force x Distance
or
We know that the `30N` force is a net force meaning friction has already been taken into account.

`W=F*d`

`W = ?`
`F=30N`
`d=9m`

`W=30N*9m`

`W = 270n*m`
