21	Horowitz, Marc		marc		6-3	3	y
	1. 48	The velocity is calculated by

		v += (-spring*(y-(radius+FLOOR)))*deltat;
            	v *= 1.0-damping;
		
		This means that the velocity used to calculate the
		damping force is the one after incorporating the spring.
		It should be the v from the previous iteration.
	2. 10	Some supporting code no demo.
