the magnitude of the component of the force that does the work is 43 n. how much work is done on a bookshelf being pulled 5 m at an angle of 37o from the horizontal?

Respuesta :

172 joules

Work = Force * times *distance

we will use the component of the force in the direction of the distance

In this problem, let’s say the distance (5.00 m) is horizontal. The horizontal component of the force is  Fcosθ

W=(Fcosθ)(D)

or

W = (43.0)(cos37.0)(5.00)

= 172Nm

=  172 Joules
