Question

Hey, try to solve this question using relative motion concepts now; by moving to the frame of the bus.
A boy stands at a distance 'd' behind the bus. The bus and boy start moving simultaneously; the boy with an initial and constant velocity of 'v' and the bus starts from rest with an acceleration of 'a' What is the minimum value of 'v' such that the boy successfully catches the bus?

A

\sqrt{2 a d}
