Answer:

100 J

Step-by-step 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

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