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 m₁ moving with a speed 2.00 m/s, collides with m2. Assume m₁ moves initially along the +x-axis. After the collision, m₁ moves with speed 1.00 m/s at an
angle of 0 = 48.0° to the positive x-axis. (Assume m₁ = 0.200 kg and m₂ = 0.300 kg.)
