An electric train accelerates uniformly from rest to a speed of 20m/s which it maintains until the brakes are applied. It is then brought to rest by uniform retardation equal in magnitude to twice its former acceleration. The total distance covered is 7.8km and the total time taken is 7 minutes. Sketch a velocity-time diagram. Calculate (a) the time taken for which the train is travelling at a constant speed, (b) the initial acceleration in m/s^2

Question
An electric train accelerates uniformly from rest to a speed of 20m/s
which it maintains until the brakes are applied. It is then brought to rest
by uniform retardation equal in magnitude to twice its former acceleration.
The total distance covered is 7.8km and the total time taken is 7
minutes. Sketch a velocity-time diagram. Calculate
(a) the time taken for which the train is travelling at a constant speed,
(b) the initial acceleration in m/s^2
