Two particles with masses 4m and 3m are moving toward each other along the x axis with the same initial speeds vi. The particle with mass 4m is traveling to the left, and particle 3m is traveling to the right. They undergo a head-on elastic collision and each rebounds along the same line as it approached. Find the final speeds of the particles.
