Two billiard balls of equal mass move at right angles and meetat the origin of an xy cordinate system. Ball A is moving upwardalong the y axis at 2.0 m/s and ball b is moving to the right alongthe x-axis with speed 3.7 m/s. After the collision, assumedelastic, ball B is moving along the positive y axis. What is the final direction of ball A and what are their two speeds?
