1.	Two cars 1 & 2 starting from rest are moving with speeds V_(1) and V_(2) m/s (V_(1) gt V_(2)). Car 2 ahead of car 'I' by 'S' metres when the driver of car '1' sees car '2' .What minimum retardation should be given to car'I' avoid collision
Answer» `(V_(1)-V_(2))/(S)` `(V_(1)+V_(2))/(S)` `((V_(1)+V_(2))^(2))/(2S)` `((V_(1)-V_(2))^(2))/(2S)` ANSWER :D
