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

Time, t = 30s

Acceleration, a = 0.5m/s^2

Distance travelled is:

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

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

$s = 600 + 225 = 825m$

Therefore , it will travel 825m....
