Answer the following questions related to two-dimensional elastic collisions where one body is initially at rest.
(a) Explain qualitatively why, for equal masses, the paths of the two bodies after collision are mutually perpendicular.
(b) Using vector diagrams, describe how momentum conservation in the x and y directions constrains the possible final velocity vectors.
(c) Discuss how the scattering angles change when the target mass is (i) greater than, (ii) less than the mass of the incident particle, keeping all other conditions identical.
(d) State two practical situations where the right-angle scattering of equal masses can be observed, and explain the underlying physics briefly in each case.
