A blue and a green billiard ball, each with a mass of 0.15 kg, collide directly. Before the collision, the blue ball had a speed of 3 m/s while the green ball had a speed of 2 m/s. After the collision, the blue ball stays in place while the green ball continues in motion.
In 3-4 sentences, represent the situation before and after the collision and calculate the speed of the green ball after the collision. Be sure to discuss direction.

Before the collision, the blue ball is moving towards the green ball at a speed of 3 m/s, while the green ball is moving towards the blue ball at a speed of 2 m/s. Both balls have a mass of 0.15 kg. After the collision, the blue ball comes to a stop and remains in place. The green ball continues moving in its original direction with a speed of 2 m/s.
