Billiard ball A, mass 0.17 kg, is moving due east with a velocity of 4.0 m/s. It strikes stationary billiard ball B, which has the same mass. After
the collision, ball A moves at an angle of 30 north of east. Ball B moves at an angle of 60 south of east with the velocity of 2 m/s. What is the
speed of ball A?
