Collisions in Two-Dimensions Suppose a mass m 1 , with initial velocity v 1i , undergoes a collision with a mass m 2 (which is initially at rest). The particles fly of at angles [theta] 1 and [theta] 2 , as shown in Figure 10.4. Since no external forces act on the collision system, linear momentum is conserved (in both x and y direction): and If the collision is elastic, kinetic energy also needs to be conserved: Figure 10.4. A Collision in Two Dimensions. The variables are: mass: m 1 and m 2 velocity: v 1i , v 1f and v 2f angle: [theta] 1 and [theta] 2 If 4 of these variables are defined, the remaining 3 can be calculated by applying conservation of energy and linear momentum. Example Problem 10-3 A beam of nuclei with mass m 1 and velocity v 1 is incident on a target nucleus with mass m 2 which us initially at rest. The velocity and scattering angles of both reaction products is measured. Determine the masses of the reaction products and the change in kinetic energy. The collision is schematically shown in Figure 10.5. Conservation of linear momentum along the
