Velocity of a train changes from 20m/s to 25m/s, when it accelerates at a rate 2m/s^2. Find the distance covered by the train.

Open in App

Solution

Use the formula V^2=U^2-2as

here V=25,U=20 and a=2

by substituting, we get
2525=2020+22s

625-400=4s

225/4=s
s=56.25
hence the distance covered is 56.25 m
