Two cars A and B are moving towards each other on a straight road with velocity 10 m s and 20 m s respectively When they are 150 m apart then car A decelerates with m s 5 and car B decelerates with 1 m s until 3 they stop in order to avoid collision If the distance in m between them when they come to rest is 15 x k then find k
