A metro train starts from rest and in five seconds achieves 108 kmh. After that it moves with constant velocity and comes to rest after travelling 45 m with uniform retardation. If the total distance travelled is 395 m, find the total time of travelling.

Answer: (D)

Solution

kmh ms. Phase 1 (accelerate 0→30 in 5 s): distance m. Phase 3 (decelerate 30→0 over 45 m):
