Question

A material particle is chasing the other one and both of them are moving on the same straight line. Their
motion after they pass a particular point is recorded and the data obtained is shown by velocity - time
graph of the particles. How long after the start will the chase end?​

Answer 1

Answer:

The correct answer

Explanation:

From the velocity–time graph, we have:

Distance covered by A = (12×t2×at2+12×t2×at2+t2×at2)=at22

Distance covered by B = (12×at×t2+at×t2+12×at2×t2)=78at2

∴ Distance covered by A < Distance covered by B
