Question

As shown in the figure, a metal ball with mass m₂ is initially at rest on a horizontal, frictionless table. A second metal 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 ? = 50.0° to the positive x-axis.

(Assume m₁ = 0.200 kg and m₂ = 0.300 kg.)

(a)

Determine the speed (in m/s) of the 0.300 kg ball after the collision.
