Acceleration on an Incline: Solving for Time and Distance

[chelseaalyssa]

Homework Statement

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

Homework 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+v_y0t+1/2a_yt²
x=x₀+v₀t

The Attempt at a Solution

Using the equation for y:
0=h + 1/2a_yt²

thanks in advance for your help!

The Attempt at a Solution

Using the equation for y:
0=h + 1/2a_yt²

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