Extracted text: Billiard ball A is moving in the y-direction with a velocity of 2 m/s when it strikes ball B of identical size and mass initially at rest. Following the impact, the balls are 30 50 observed to move in the directions shown. Calculate the velocities v, and v8 which the balls have immediately after the impact. Treat the balls as particles and neglect any friction forces acting on the balls compared to the force of impact. B 2 m/s Write the linear-impulse momentum relation in the y direction.
