Lumage: The air resistance in your code automatically limits how high  can go. Imagine  is 10... the next assignment will be   giving the result of... 10! If somehow, you were falling faster than terminal velocity, say at speed 15, the next assignment will be, or 14.5... you will slow down to terminal velocity. So, you can omit that last !
