a billiard ball physics question

As shown in the figure, a billiard ball with mass m2 is initially at rest on a horizontal, frictionless table. A second billiard ball with mass ml moving with a speed 2.00 m/s, collides with m2. Assume ml moves initially along the +X-axis. After the collision, m1 moves with speed 1.00 m/s at an angle of 9 = 510° to the positive x—axis. (Assume m1 = 0.200 kg and m2 = 0.300 kg.)
