    Two dimensional collisions
    A stationary billiard ball, with a mass of 0.17 kg, is struck by an identical ball moving at 4 m/s. After the collision, the second ball moves 60 degress to the left of its original direction. The stationary ball moves 30 degrees to the right of the moving ball's original direction. What is the velocity of each ball after the collision?
