a block slides along a horizontal plane at an initial velocity of 10m/sec. After sliding 4 meters it reaches a 35 degree incline and slides up the hill. the coefficient of kinetic friction is 0.4 for all surfaces.

a) how fast is it going when it reaches the incline?
b) how far up th incline will it slide?
c) what is the total time from start to its highest point?

Is this for the first part? Re-read the question; the block is on a horizontal plane, thus what is the value of v0? Is there a force acting on the block? What does this say about your statement that there is no acceleration?

It's also probably best to let x0=0 and let xf=4.

Think about my questions and the part of the problem you want to answer, and show some work; not just a list of given quantities.
