Solving for g on an inclined plane

[mysticbms]

Homework Statement

Solve for g in terms of d, t, and theta on an inclined plane.

Homework Equations

Fnet=ma and d=Vit + .5a*t^2

The Attempt at a Solution

Solving for a on an inclined plane I get g*sin theta.

Using the equation for constant acceleration d=Vit + .5a*t^2 I solve for g.

Vi is 0 on an initial plane so I have d=.5(g*sin theta)t^2

g=2d/(sin theta*t^2)

Is this correct?
