Two particles with masses 2m and 5m are moving toward each other along the x axis with the same initial speed, vi. Particle 2m is traveling in the ?x direction and particle 5m is traveling in the +x direction. They undergo an elastic glancing collision such that particle 2m is moving in the +y direction after the collision.
(a) Find the final speeds of the two particles after the collision. Define all quantities so that I can understand which speed applies to each particle.
(b) What is the angle ? of the 5m mass, measured from its initial direction in the +x direction? Draw me a picture of this angle so that I can see how you define this angle.
