Two trains face each other on adjacent tracks. They are initially at rest, and their front ends are 36 m apart. The train on the left accelerates rightward at 1.1 m/s2. The train on the right accelerates leftward at 0.99 m/s2.
(a) How far does the train on the left travel before the front ends of the trains pass?
(b) If the trains are each 150 m in length, how long after the start are they completely past one another, assuming their accelerations are constant?
