Answer to Question #289532 in Physics for Mom

Question

How much work is done on a bookshelf being pulled with a force of 53.8 N for a distance of 5.00 m at an angle of 37.0o from the horizontal?

Answer 1

Given:

$F=53.8\:\rm N$

$d=5.00\:\rm m$

$\theta=37.0^\circ$

The work done

$$W=Fd\cos\theta=\rm 53.8*5.00*\cos37^\circ=215\: J$$
