Question

A force of 100 N is applied to a crate at an angle of 60° to the horizontal surface. The force causes the crate to move 2 m across the floor. How much work is done on the crate?

Answer 1

Answer:

100 J

Explanation:

The work done by the force on the crate is given by

$W=Fd cos \theta$

where

F = 100 N is the magnitude of the force

d = 2 m is the displacement of the crate

$\theta=60^{\circ}$ is the angle between the direction of the force and the displacement

Substituting, we find

$W=(100 N)(2 m)(cos 60^{\circ})=100 J$

Answer 2

I just took it, got 100. its right.
