A bungee jumper leaps from a bridge and undergoes a series of oscillations. Assume g = 9.78 m/s2.
(a) If a 60.0-kg jumper uses a bungee cord that has an unstretched length of 33.0 m and she jumps from a height of 50.0 m above a river, coming to rest just a few centimeters above the water surface on the first downward descent, what is the period of the oscillations? Assume the bungee cord follows Hooke's law.
(b) The next jumper in line has a mass of 80.0 kg. Should he jump using the same cord? Explain.
