hey all(adsbygoogle = window.adsbygoogle || []).push({});

i have this very annoying physics problem that ive been looking at for hours.

In the physics laboratory, a glider is released from rest on a frictionless air track inclined at an angle. If the glider has gained a speed of 22.0 cm/s in traveling 40.0 cm from the starting point, what was the angle of inclination of the track? Assume that the initial velocity is zero.

I understand that you have the initial velocity and the final velocity, and you can find the acceleration with a "constant acceleration" equation, specifically DeltaX= 1/2acceleration*time squared, but how on earth do you find the angle of inclination given only the value for x, and not for y or the hypotenuse?

Someone please help!!!!!!
