A bungeejumper of mass m = 77.7 kg steps off a platform a height h = 50.0 m above the ground. The bungeejumper is connected to the platform by a bungee cord with unstretched length L = 10.0 In and spring constant k = 87.0 N m1 . You should assume that the impact of air resistance is negligible in this question. Part 1) At what speed is the person travelling after they have fallen a distance 20.0 m from the platform? I) = m 51 Part 2) If the total distance fallen by the person is given by d, write an algebraic expression for the magnitude of the work done by the bungee cord during the fall in terms of the variables 0', k, and L. IWI = J Part 3) What is the maximum distance below the platform that the person reaches during their fall? d: m
