A car A has just overtaken car B which is moving in the same direction

1.	A car A has just overtaken car B which is moving in the same direction as A. Gien below are few cases explanainig the motion of the cars at that instance. Identify th given cases as cases that are necessarily true, cases that can be true only under certain conditions and cases that are necessarily false. (i) The car is accelerating and car B isb decleariting (ii) The car A is decelearting and car B accelerating (iii) Both car accelerating (iv) Both cars are decelerating (v) Both cars moving with uniform velocity (vi) Car A is moving with uniform velocity and car B is accelerationg. (vii) Instantaneous spee of car A is less than that of car B (viii) Instaneous speed of car B is less thatn that of car A.
Answer» What is instantaneous velocity? When car A just overtaken car B, which one has higher insaneous velocity? If the instaneous velocity of A is greater than that of B, then is it a must that it should be accelerated or decelerated? Is it not possible that both the cars have acceleration or deceleration or more with uniform velocity?
