4) Two subatomic particles collide. Initially, the more massive particle (A) is at rest and the less massive particle (B) is moving. After the collision, the velocities of A and B make angles of 67.8' and 30.0", respectively, to the original direction of B's motion. The ratio of the final speeds of the particles ve / VA is 3.30. What is the ratio of the masses of the particles ms / mA
