Answer:
3 Newtons
Explanation:
The work done by Kendall is given by:
[tex]W=Fd[/tex]
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:
[tex]F=\frac{W}{d}=\frac{30 J}{10 m}=3 N[/tex]
