Acceleration down an incline

  1. Sep 13, 2009 #1
    1. The problem statement, all variables and given/known data
    An object is released (from rest) at the top of an inclined plane. After time t, the object has moved a distance d down an incline. What is its acceleration


    2. Relevant equations
    There is some stuff written in regards to this question about using only time and distance to calculate the acceleration - so that leaves the equations:
    y=y0+vy0t+1/2ayt2
    x=x0+v0t

    3. The attempt at a solution
    Using the equation for y:
    0=h + 1/2ayt2

    thanks in advance for your help!

    Write it in terms of distance d. (I'd say that y0 = 0 and y = d.) Just call the acceleration a.
