Question

The driver of a train travelling at 40 m/s applies the brakes as a train enters a station. The train slows down at a rate of 2 m/s^-2. The platform is 400 m long. Will the train stop in time?

Answer 1

Answer:

Complete answer:

It is given that the train slows down as it approaches a station. It is given that the train slows down at a rate of 2ms−2. This means that when the driver applies the breaks, the train undergoes retardation. It is given that the initial velocity of the train is 40m/s.

Answer 2

Answer:
