Problem 14.23 A bungee jumper with mass 70.0 kg jumps from a high bridge. After reaching her lowest point, she oscillates up and down, hitting a low point eight more times in 50.0 s. She finally comes to a rest 25.0 m below the bridge. Find the spring constant and the unstretched length of the bungee cord.Sketch the situation, defining all your variables.What physics equation(s) will you utilize in order to solve this problem? For each equation you list, give a justification for why it applies to this situation.Apply your equation(s) to solve, first for an algebraic expression(s), then for any numerical answer(s). Show the units of your answer(s), and how you got them. Present your work clearly and neatly.
