A 2.0 kg ball moving at 10 m's makes an off-center collision with a 3.0 kg ball that is initially at rest. After the collision, the 2.0 kg ball is deflected at an angle of
30° from its original direction of motion and the 3.0 kg ball is moving at 4 m/s
Find the speed of the 2.0 kg ball and the direction of the 3.0 kg ball after the
collision
