Question

Kendall does 30 Newton-meters of work pushing her sofa halfway across the living room. Her living room is 10 meters

long. How much force did Kendal use?

30 Newtons

10 Newtons

3 Newtons

unknown

Answer 1

3 Newtons

Step-by-step explanation:

The work done by Kendall is given by:

`W=Fd`

where

F is the force

d is the displacement of the sofa

In this problem, we know

W = 30 Nm = 30 J

d = 10 m

So we can solve the formula for F to find the force used by Kendal:

`F=(W)/(d)=(30 J)/(10 m)=3 N`
