Two cars 1 & 2 starting from rest are moving with speeds V_1 and V_2"

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 is ahead of car .1. by .S. metres when the driver of car .1. sees car .2.. What minimum retardation should be given to car.l.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
