## Homework Statement

A block of mass is pushed up an incline

of width d and height h with coefficient of friction μk

up to the top of the incline by a constant applied force of

magnitude F parallel to the ground. The block begins

at rest.

## Homework Equations

f=ma

w = f . d

## The Attempt at a Solution

if i choose a coordinate system with an x axis Parrnell to the incline plane, then would it go like this:

normal force work= 0

applied force work = Fd/cos(60) <-- not sure about this one, my prof just wrote Fd in class, but i didnt understand why

work by fric = -ukmgd

work done by gravity = -mgh

is this right?
