Two particles with masses 2m and 9m are moving toward each other along the x axis with the same initial speeds vi. particle 2m is traveling to the left, while particle 9m is traveling to the right. they undergo an elastic, glancing collision such that particle 2m is moving in the negative y direction after the collision at a right angle from its initial direction. (a) find the final speeds of the two particles in terms of vi. particle 2m ✕ vi particle 9m ✕ vi (b) what is the angle θ at which the particle 9m is scattered? °
