%% Bouncing Ball Model: Use of Zero Crossing Detection
% 
% A rubber ball is thrown into the air with a velocity of 15
% meters per second from a height of 10 m.  The position
% of the ball is shown in the lower plot of the scope, and 
% the velocity of the ball is shown in the upper plot.
% 
% This system uses a reset integrator to change the
% direction of the ball as it comes into contact with
% the ground, the zero crossing detection prevents the
% ball from going below the ground.
