Unformatted text preview: decrease in their yvelocitycomponents. This leads to smaller angles of scattering. Consequently, one particle travels through region B , the other through region C ; the paths are symmetric about the xaxis. We note that this is intermediate between the final states described in parts (b) and (a). (d) Conservation of momentum along the xaxis leads (because these are identical particles) to the simple observation that the xcomponent of each particle remains constant: v f x = v cos = 3.06 m/s. (e) As noted above, in this case the speeds are unchanged; both particles are moving at 4.00 m/s in the final state....
