Two basketball players are essentially equal in all respects. (They are the same height, they jump with the same initial velocity, etc.) In particular, by jumping they can raise their centers of mass the same vertical distance, H (called their 'vertical leap'). The first player, Arabella, wishes to shoot over the second player, Boris, and for this, she needs to be as high above Boris as possible. Arabella jumps at time t = 0, and Boris jumps later, at time tR (his reaction time). Assume that Arabella has not yet reached her maximum height when Boris jumps.(a) Find the vertical displacement D(t) = hA(t) - hB(t), as a function of time for the interval 0 < t < tR) where hA(t) is the height of the raised hands of Arabella, while hB(t) is the height of the raised hands of Boris. Express the vertical displacement of H, g, and t.(b) Find the vertical displacement D(t) between the raised hands of two players for the time period after Boris has jumped (t > tR) but before Arabella has landed. Express your answer in terms of t, tR, g, and H.
