## Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. One is moving upward along the y-ax?

Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. One is moving upward along the y-axis at 3.00 m/s, the other is moving to the right along the x-axis with speed 4.80 m/s. After the collision (assumed elastic), the second ball is moving along … Read more
