1. The problem statement, all variables and given/known data Find an analytical model for the height of a bouncing ball to be able to find the the height of the ball at any given time. In other words, as I understand, write an equation that would define the trajectory of a bouncing ball. Let's say the coefficient of restitution (COR) is 0.9 (it's a table tennis ball) 2. Relevant equations 3. The attempt at a solution Im kinda stuck on this, this is a bit beyond me, but I thought maybe somehow transforming the absolute value of y=cos(x); or using a bunch of quadratic equations to represent each bounce, but that doesn't seem right.
