A bungee jumper attains a speed of 128 km/hr (35.6 m/s) before the tension in the bungee cord begins to slow the jumper down. Once the bungee cord starts developing tension, it takes 6 seconds before the tension is great enough to start pulling the jumper up. a) Assuming negligible air resistance, what is the time duration?

and b) distance of free fall? c) What is the average acceleration of the jumper after the bungee develops tension?
