Ball A with a mass of 0.500 kg is moving east at a velocity of 0.800 m/s. It strikes ball B, also of mass 0.500 kg, which is stationary. Ball A glances off B at an angle of 40.0° north of its original path. Ball B is pushed along a path perpendicular to the final path of ball A.
(a) What is the momentum of ball A after the collision?
(b) What is the momentum of ball B after the collision?
(c) What is the velocity of ball A after the collision?
(d) What is the velocity of ball B after the collision?
