NEET Physics QUESTION #7312

Question 1

A bus moves at $10\text{ m/s}$ on a straight road. A scooterist at a distance of $1\text{ km}$ behind wants to overtake the bus in $100\text{ s}$. The minimum speed required is:

$10\text{ m/s}$
$20\text{ m/s}$✔️
$40\text{ m/s}$
$25\text{ m/s}$

Correct Answer Explanation

In 100 s, the bus moves: $10 \times 100 = 1000\text{ m}$

Total distance scooterist must cover: initial gap + bus distance $= 1000 + 1000 = 2000\text{ m}$

Speed $= \dfrac{2000}{100} = \mathbf{20\text{ m/s}}$
