Instead its by pixels to the right of the screen size to do believe 352-001 arithmetic to figure out what that is cut the cornerstone the guy on the left is going to get ashore otherwise I'm not going to do anything in less they cornet is actually really close to the top of the wall or really close to the bottom of the wall in which case I'm going to perform a reflection with just a little bit arithmetic wherein flip around don't the velocities y component so that you’re going five miles per hour this way now you're going to get a five miles per hour so as to flip the ball in a reverse direction so the end result here all end up at all is similar .
