Answer:
100 J
Explanation:
The work done by the force on the crate is given by
[tex]W=Fd cos \theta[/tex]
where
F = 100 N is the magnitude of the force
d = 2 m is the displacement of the crate
[tex]\theta=60^{\circ}[/tex] is the angle between the direction of the force and the displacement
Substituting, we find
[tex]W=(100 N)(2 m)(cos 60^{\circ})=100 J[/tex]
