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 car 1 by a meter when the driver of the car 1 sees car 2 what minimum retardation should be given to car 1 to avoid collision.

Two cars 1 & 2 strating from rest are moving with speeds V_1 and V_2m//s (V_1 > V_2) . Car 2 is ahead of car '1' by 'S' meters when the driver of car '1' sees car '2' . What minimum retardation should be given to car '1' avoid collision.

Two car A and B travelling in the same direction with velocities v_1 and v_2(v_1 gt v_2) . When the car A is at a distance d ahead of the car B , the driver of the car A applied the brake producing a uniform retardation a . There wil be no collision when.
