Question

A train is moving with a velocity of 90km/h. When the driver applies brakes the train comes to halt in 10seconds. Calculate the distance covered by the train in 10 seconds

Answer 1

Answer:

Explanation:use V=u-at to find out acceleration(a),as V=final velocity=0, we get 0=90/60×60 -a×10 or a=1/40

Now putting in S=ut-1/2at^2

We get S=1/4×10-1/2×1/40×100

Or S =5/4 km
