One billiard ball (mass 118 grams) is moving due east at 5.0 m/s. A tennis ball (mass 321 grams) is moving due west at 4.0 m/s. The two balls have a glancing blow, which means they do not bounce along the same line as their original motion, but rather, deflect at an angle to their original paths. You measure the billard ball's motion as it moves 26.0° north of east, and you measure that the tennis ball is travelling 19.0⁰ south of west. What is the speed of the billiard ball after the collision?
