Develop a code simulating a system of two non-interacting particles (two hard spheres of same radii r) confined in a CIRCULAR shaped box of radius R with reflecting boundaries, which is held at constant temperature T. Past the code in your answer sheet with three images/screen shots, 1) screen shot of your input data, r, R, and T, 2) image of the hard sphere just before hitting the circular boundary, 3) image of the hard sphere just after bouncing back from the circular boundary. Also draw circles on 2nd and 3rd images to show the circular boundary. (Hint: take molecular dynamics code which we developed in class for hard spheres and modify it for circular reflecting boundary. Use Jmol to watch movie and obtain screen shots of hard spheres before and after hitting the circular walls.)
