Two cars `1` and `2` move with velocities `v_(1)` and `v_(2)`, respectively, on a straight road in same direction When the crs are separated by a destance `d` the driver of car `1` applies brakes and the car moves with uniform retardation `a_(1)`, Simultaneously, car `2` starts accelerating with `a_(2)`, If `v_(1) lt v_(2)`, find the minimum initial separation between the cars to avoid collision between then.
