A blue billiard ball (2kg) with initial speed 6 m/s collides with another red billiard ball (3 kg) moving in the same positive x - axis. After the collision, the first ball bounces off with speed √4 m/s in a direction that makes an angle +30o with the original direction. The second ball bounces in a direction that makes an angle θ2 on the other side of the first ball’s original direction. Neglect friction. Use the x-y coordinate system shown.
