## Homework Statement

If the height of a frictionless incline is h. Determine the work done by the force due to gravity F as the crate of the mass m slides down the incline

## Homework Equations

W=Fd cos (theta )

Force due to gravity perpendicular to incline= mg cos(theta)

## The Attempt at a Solution

The solution doesn't have any mention of cosine theta or any consideration of the angle of the incline. Please explain why this would be.

The solution simply states that

W=FD and F=-mg therefore W=mgh
