Passage / Comprehension

A car travelling at constant velocity, passes a stationary motor cycle at a traffic light. As the car overtakes the motorcycle, the motorcycle accelerates uniformly from rest. The following displacement-time graph represents the motions of both vehicles from the traffic light onwards.

Choose the correct statement(s) :-

Options:(select one or more)

Answer:

A, B

Solution:

They will meet when their position will same.

X for car $= v \times t$ (v is speed of car)

X for motorcycle $= vt + \frac{1}{2} at^{2}$

(v initial speed \& a acceleration of motor cycle)

$v \times t = 0 + \frac{1}{2} at^{2}$
