A passenger train is moving with speed v1 on rails. The driver of this train observe another goods train moving in the same direction v2(v1>v2). If on applying brakes, the retardation produced is a, then the minimum distance covered by the passenger train so that if may not collide with the goods train will be
(a) (v12 –v2) /2a
(b) (v1+v2)2 /2a
(c) (v1-v2)2 /2a
(d) Information is incomplete.
