Question

A train travelling at 30 ms -1. accelerates at 0.5ms-1 for 30s.​

Answer 1

Answer:

Proper question :-

A train travelling at 30 ms -1. accelerates at 0.5ms-1 for 30s. How far will it travel in this time ?

SOLUTION :-

Initial velocity, u=20m/s

Initial velocity, u=20m/sTime, t=30s

Initial velocity, u=20m/sTime, t=30sAcceleration, a=0.5m/s^2

Distance travelled is:

$s = ut + \frac{1}{2}a {t}^{2}$

$s = 20 \times 30 + \frac{1}{2} \times 0.5 \times 30 \times 30$

$s = 600 + 225 = 825m$

Hence , it will travel 825 m...
