Each croquet ball in a set has a mass of 0.52 kg. The green ball, traveling at 13.1 m/s, strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless 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.

b) The green ball continues moving after the collision at 2.7 m/s in the same direction.

c) The green ball continues moving after the collision at 0.2 m/s in the same direction.
