Two 110 meter long trains are traveling at 23.5 m/s, going in opposite directions on parallel tracks.
A) Find how much time elapses from the moment the front ends of the trains pass to when the rear ends pass?
B) Repeat part A, but this time supposes that when the front ends pass, one train begins to accelerate at 1.0 m/s2.
