Two cars 1 & 2 starting from rest are moving with speeds V_1 and V_2 m//s (V_1 gtV_2). Car 2 is ahead of can '1' by 'S' metres when the driver of car '1' sees car '2'. What minimum retardation should be given to cart avoid collision

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

1.	Two cars 1 & 2 starting from rest are moving with speeds V_1 and V_2 m//s (V_1 gtV_2). Car 2 is ahead of can '1' by 'S' metres when the driver of car '1' sees car '2'. What minimum retardation should be given to cart 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
