A glider of length 12.3 cm moves on an air track with constant acceleration. A time interval of 0.637 s elapses between the moment when its front end passes a fixed point A along the track and the moment when its back end passes this point. Next, a time interval of 1.27 s elapses between the moment when the back end of the glider passes point A and the moment when the front end of the glider passes a second point B farther down the track. After that, an additional 0.354 s elapses until the back end of the glider passes point B.
(b) Find the acceleration of the glider.
