Each croquet ball in a set has a mass of 0.45

kg. The green ball, traveling at 12.6 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.
