(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A proton is shot horizontally at a nucleus on a cartesian plane, a distance B above the nucleus. It is deflected upwards in a hyperbolic path and its path becomes parallel to another ray out of the nucleus, distance A away from this ray. Show that A=B using conservation of angular momentum. Assume that the nucleus does not move and that the collision is perfectly elastic.

2. Relevant equations

Angular Momentum = Moment of Inertia x Angular Velocity

3. The attempt at a solution

I have no bloody idea where to start.
