Help....glider on an airtrack problem In the physics laboratory, a glider is released from rest on a frictionless air track inclined at an angle similar to the one shown in the figure below . If the glider has gained a speed of 24 cm/s in traveling 50 cm from the starting point, what was the angle of inclination of the track? Ok, what I have done is I figured out the acceleration to be 5.76. Would that be correct? And now I am having trouble trying to get the angle...I am not sure what to do. Please help.
