let's see;
if you throw a ball into the wall, the ball will cover half the distance X first right? then the half of the remaining distance, then the half etc..
X\2 + X\4 + ... + X\n = X only when n is inf. so the ball ill never hit the wall
but yet my ball bounced of the wall into my face
i need
mathematical verification that the ball CAN and WILL hit the wall, any thoughts?
