1.	of(ii) telocity of a train changes from 20m/s to 25 mn when it accelentes dii2s Find the distance covered by the train
Answer» Use the formula: v^2=u^2+2as Where v is the final velocity = 25 m/s u is initial velocity = 20 m/s a is the acceleration = 2m/s^2 s is the distance traveled. Substitute the above values in the equation of motion to get s = (625 - 400)/4 = 56.25 m

Answer»

Use the formula:

v^2=u^2+2as

Where v is the final velocity = 25 m/s

u is initial velocity = 20 m/s

a is the acceleration = 2m/s^2

s is the distance traveled.

Substitute the above values in the equation of motion to get s = (625 - 400)/4 = 56.25 m
