Each croquet ball in a set has a mass of 0.55 kg. the green ball, traveling at 14.6 m/s, strikes the blue ball, which is at rest. assuming that the balls slide on a friction- less surface and all collisions are head-on, find the final speed of the blue ball in each of the following situations: a) the green ball stops moving after it strikes the blue ball. answer in units of m/s. b) the green ball continues moving after the collision at 2.1 m/s in the same direction. answer in units of m/s. c) the green ball continues moving after the collision at 0.3 m/s in the same direction. answer in units of m/s
