bungee jumper, an 70-kg man, falls from the bridge at A with the bungee cord secured to his ankles. He falls 20 m before the 17-m length of elastic bungee cord begins to stretch. The 3 m of rope above the elastic cord has no appreciable stretch. The man is observed to drop a total of 44 m before being projected upward. Neglect any energy loss and calculate (a) the stiffness k of the bungee cord (increase in tension per meter of elongation), (b) the maxi-mum velocity vmax of the man during his fall, end (c) his maximum acceleration amax. Treat the man as a particle located at the end of the bungee cord
