A police man is running towards a thief with a constant acceleration of 0.1m/s². At a particular instant t = 0, the policeman is 20m behind the thief and at that instant the velocity of policman is 4m/s. At this instant the thief observes, the policeman coming towards him. So, he starts running away from the policemen in the same direction with a constant acceleration. Then what is the minimum constant acceleration with which the thief should run so that he is not caught? A 0.2m/s² B 0.4m/s² C 0.5m/s²
