Question

the train is travelling at a speed of 90 km/hr. Brake are applied so as to produce a uniform acceleration of -0.5 m/s

Answer 1

Explanation:

Initial velocity = 90km/h or 25m/s

final velocity= 0m/s

acceleration= -.5m/s sq.

time= ?

Now, using a= v-u/t

t= v-u/a

t= 0-25/-.5

t=25/.5

t=50s

Therefore time taken= 50s

Answer 2

Answer:50 seconds is the answer to ur question. ..

Hope it helps...
