Question

A train is travelling at a speed of 72km/hr. on applying the brakes, a uniform

retardation 0.5m/ses2

is produced. Find how far the train will go before it is brought

to rest?​

Answer 1

Answer:

Given that, the initial velocity (u) ofthe train is 72 km/hr. The driver applies brakes so that a Uniform acceleration of -0.2m/s² is produced. We have to find the distance (s) travelled by train before it comes to rest. Therefore, the distance travelledby train before it comes to rest is 1000 m or 1 km.
