After a thrilling plunge, bungee-jumpers bounce freely on the bungee cord through many cycles (Fig. P15.22) After the first few cycles, the cord does not go slack. Your little brother can make a pest of himself by figuring out the mass of each person, using a proportion which you set up by solving this problem: An object of mass m is oscillating freely on a vertical spring with a period T. An object of unknown mass m7 on the same spring oscillates with a period T7. Determine (a) the spring constant and (b) the unknown mass.
