3. Consider a perfectly elastic collision between two particles. Initially the 1st particle with a mass, m, is moving in the x-direction with a velocity, v₁, and the 2nd particle with mass, M is at rest. After the collision, the 1st particle has a purely y-directional velocity. Determine the velocity components for both particles following the collision and the kinetic energy of the 2nd particle (The one initially at rest). Consider the cases of: a) an electron striking a hydrogen atom, b) an electron striking a xenon atom, and c) a xenon atom striking another xenon atom. For each case assume the incident particle velocity is 5000 m/s.
