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

100 J

Step-by-step explanation:

I did it on EDGE 2021

Answer 2

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`
