A train, starting from rest from station A, travels along a straight horizontal track until it stops at station B, which is 2400 m from A. Initially, the train accelerates at a uniform rate of 0.4 ms–2 until it reaches a speed of 16 ms–1. It then maintains this speed of 16 ms–1 for T s, before decelerating uniformly to rest in 20 s.

  1. Calculate the time taken for accelerating.
