Homework Help: Object going up inclined plane with friction, how far does it go?

  1. Feb 18, 2010 #1
    1. The problem statement, all variables and given/known data
    A box is sliding up an incline that makes an angle of 15 degrees with respect to the horizontal. The coefficient of kinetic friction between the box and the surface of the incline is .180. The initial speed of the box at the bottom of the incline is 1.50 m/s. How far does the box travel along the incline before coming to rest?

    2. Relevant equations

    3. The attempt at a solution
    the book this problem came from refered to an example where they were on a flat surface and they used x=(v2-vo2)/2(-.18*9.8). I have no idea how to incorporate the 15 degree incline into my answer, the solution in the book says .265m if that helps.

    Make a diagram of all the forces acting on the object, then consider which are slowing it down in it's ascent up the ramp. You'll need to use trig.
