The coefficient of restitution is a parameter of a ball surface and reflects the fraction of velocity just after the bounce divided by the velocity just before. These equations describe four consecutive stages of My model predicts that a driver hitting a ball at 72. Thus after the ball hits the floor for the first time the ball rises to a height of 10 3 4 7. Since the ball can go either of two directions up or down we will need to A mathematical model for the evolution of the still unspeci ed quantity ancould take the form an 1 an In words the new value is a scalar multiple of the old value o set by some constant . This lab will guide you through all of the steps. It is based on the integro differential equations for the contact motion and Stefan problem for the temperature field. The coefficient of restitution is the velocity of the ball after the bounce divided by the velocity before the bounce. The core is a TL074 opamp that does all the integral math. where yrepresents the rebound height xrepresents the bounce number his the release height andpis a constant that depends on the physical characteristics of the ball used. Feb 23 2020 Therefore the aim of this study was to produce a model to measure energy expenditure while bouncing on a trampoline. By using 3D animation you can get a much better understanding of the deformation of the ball. exponential mathematical model of the bouncing ball will be confirmed although I did not know this before the experiment. If you get REALLY lucky you might even land in the end zone with the ball in hand. We will develop a mathematical model for this ball then use a computer program to translate that into a virtual model. They re all bouncing around and coming into contact with others. In Model a ball bouncing down steps and plot its total kinetic and potential energy. The ground exerts more force on the ball that bounces than the ball that stops. In between bounces the ball is a projectile in free fall so it 39 s trajectory will probably not be constant but how it changes at each bounce is hard to model. To achieve this the study was completed in two stages. From the workspace you can open the Simulink Library Browser as shown in Figure 1. You can use the walls around the screen to bounce balls into place. k T i a i k u DA 0 u MU u k y x 0 x k AD MUy 0 y MU 0 y sensor k c m k F g F a F m g k fv x0 ball and coil A D converter D A converter power amplifier Figure 2.
