[Qs-Home---]: As a newly hired engineer at "Toys R Them" your boss hands you over a smartphone and a super bouncy ball, manufactured from cutting edge material. Find a way to use your smartphone to estimate how many bounces this ball can make. Simulate the experiment and show results with any ball you can find (and actual data from your smartphone).
