ou accompany your young cousin and her best friend Abigail to the Capitol Hill People's Fair. Both good little girls want to ride on the "bungee seat" (or whatever that thing is called), in which the rider bounces up and down (with simple harmonic motion, of course) while sitting on a seat supported by springs (see diagram). 

You accurately measure the frequency of your young cousin's bounces to be 0.343 Hz, and that of Abigail's ride to be 0.305 Hz. Knowing the mass of your young cousin (26.3 kg), you can (and should now) determine Abigail's mass. 


A) 30.5 kg 


B) 31.9 kg 


C) 32.6 kg 


D) 33.3 kg 


E) 34.8 kg
