Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Initially ball A is moving upward along the y axis at 2.0m/sm/s, and ball B is moving to the right along the x axis with speed 3.7m/sm/s. After the collision (assumed elastic), the second ball is moving along the positive y axis. What is the final direction of ball A? Express your answer using two significant figures.
