SO, I have a question: A block of mass 15.0 kg starts from rests and slides down an incline plane with slope angle 45 degrees for distance1. It then reaches the flat surface and travels for a distance2 where it comes to rest. The coefficient of kinetic friction between the block and all surfaces is the same everywhere with a value 0.200.
Drawing coming up in a bit.

Okay, soooo I did the whole free body diagram thing and got the sum of the forces of the x and y coordinates...but then I get stuck on something.

I got Fx=-Friction+Fgravitysin(theta)=ma 

and then i got Fy=Normal force-Fgravitycos(theta)=ma
