Question

A train is travelling at a speed of 90 km/hr. Brakes are applied which produces uniform
acceleration of -0.5 m/s2
. Find how far will the train go before it is brought to rest.

Answer 1

Answer:

The train will go 50 kilometer far before it will come to rest.

Explanation:

Given, Speed of the train = 90 km/h

Uniform acceleration = - 0.5 m/s = - 1.8 km/h

Let the speed be V

And, the uniform acceleration be U

Hence, before the train is brought to rest, it will go V / U = (90 / 1.8) km = 50 kilometer. (answer).
