Yeah I did that however the unfortunate thing is that this has no answer key so I cannot even check. Regardless, you were extremely helpful, thank you!
Sorry, that's my imagination talking, I imagined the ball and track inside a car and the car is moving to the left in this case. You are right there is no horizontal force acting on the ball but, when the "car" reaches constant acceleration, the ball should be stuck at one point, where the Fnet...

Thanks, I think I got it. Sorry for the bad quality photos, my webcam is the only camera I have when doing late night physics :P

Homework Statement
A block of mass m is at rest at the origin at t = 0. It is pushed
with constant force Fo from x = 0 to x = L across a horizontal
surface whose coefficient of kinetic friction is μk = μ0(1 - x/L).
That is, the coefficient of friction decreases from μ0 at x = 0 to
zero...
