Two cars a and b are travelling in the same direction with velocities v, and v, (v, > v½). When the car a is at a distance behind the car b, the driver of car a is at a distance behind the car b, the driver of car a applies breaks producing a uniform retardation f. There will be no collision when (a) d>(v, -v, /2f (b) d>(v, -v,)* /2s (c) d>(v, -v,)*/25 (d) d<(v, -v,)* /12f
