Each croquet ball in a set has a mass of 0.49 kg. The green ball, traveling at 13.7 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:

1) the green ball continues moving after the collision at 2.9 m/s in the same direction.

2)the green ball continues moving after the collision at 0.3 m/s in the same direction
