A crate of oranges slides down an inclined plane without friction. If it is released from rest and reaches a speed of 4.476 m/s after sliding a distance of 2.33 m, what is the angle of inclination of the plane with respect to the horizontal?

physics 
bobpursley,
vf^2=2ad
solve for a.
then,
g*sinTheta=a
solve for theta.
