Two cars 
and 
are moving on a road in the same direction. Accleration of car 
increases linearly with time whereas car 
moves with a constant accleration. Both cars cross each other at time 
, for the first time. The maximum possible number of crossing(s) (including the crossing at 
) is .
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION
(3) 
is constant
is constant
as initial velocities are not mentioned in question, so will have to assume two cases.
Case-I
and 
in same direction
Total number of crossing 
Case-II
and 
in opposite direction
Total number of crossing
