Explanation:
This applet illustrates elastic collisions of two point masses as discussed in Section 8.3. The masses are set equal to each other. You can view the results in both the lab's frame of reference or the center-of-mass frame of reference. As shown in example 8.3, knowing the ratio of the projectile's final speed to its initial speed is sufficient for determining both scattering angles.
