At this point, the direction changes (the new une 21, angle will equal the negative of the angle at impact), and the PROBLEMS to do this velocity will decrease in magnitude to reflect energy loss function due to the collision of the ball with the ground. The change % functi in velocity can be quantified by the coefficient of restitution C which is equal to the ratio of the velocity after to the ve- locity before impact. For the present case, use a value of C,-0.8 3.22 Develop a function to produce an animation of a parti- cle moving in a circle in Cartesian coordinates based on ra- dial coordinates.
