A ball is held at rest at some height above a horizontal surface. Once the ball is released at time t = 0, it falls under gravity, hits the surface at time t = T1 and starts bouncing up and down vertically. Suppose that with each bounce the ball loses a fixed fraction p of its energy (with 1>p>0). This loss could be due to a number of reasons (inelasticity, drag, etc) that are left unspecified. How many times will the ball bounce before coming to rest? Provide a detailed explanation of your reasoning, not simply a one-line answer. How long will it take for the ball to come to rest (if at all), i.e., what is the stopping time Tstop? Give your answer for Tstop as a single formula that contains only two independent variables, namely the fractional energy loss p and the time T1 .
