Two particles move perpendicular to each other until they collide. (Figure below) Particle 1 has mass 2m and momentum of magnitude 2p, and particle 2 has mass 3m and momentum of magnitude p. Note: Magnitudes are not drawn to scale in any of the figures. Suppose that after the collision, the particles "trade" their momenta, as shown in the figure. That is, particle 1 now has magnitude of momentum p, and particle 2 has magnitude of momentum 2p; furthermore, each particle is now moving in the direction in which the other had been moving. How much kinetic energy, Klost, is lost in the collision? p After collision 2m 2m 3m 2p 2p Before collision 3m Op O V3p Am O 3p Am O 0 7p
