A billiard ball physics question

As shown in the figure, a billiard ball with mass m is initially at rest on a horizontal, frictionless table. A second billiard ball with mass m 1 moving with a speed 2.00 m/s, collides with m . Assume m 1 moves initially along the +x-axis. After the collision, m 1 moves with speed 1.00 m/s at an angle of \(\theta = 51.0^o\) to the positive x-axis. (Assume m 1 = 0.200 kg and

* Determine the speed (in m/s) of the 0.300 kg ball after the collision.
* Find the fraction of kinetic energy transferred away or transformed to other forms of energy in the collision.
