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?
