Ball A, with a mass of 1.75 kg, moves with a velocity 3.50 m/s. It collides with
a stationary ball B, with a mass of 2.50 kg. After the collision, ball A moves in
a direction 55.0° to the left of its original direction, while ball B moves in a
direction 35.0° to the right of ball A's original direction. Calculate the velocity
of each ball after the collision.
