1) An elastic cord is 63.9 cm long when a weight of 71.1 N hangs from it but is 88.9 cm long when a weight of 184 N hangs from it. What is the "spring" constant k of this elastic cord?

2) A small fly of mass 0.243g is caught in a spider's web. The web vibrates predominately with a frequency of 3.94 Hz. What is the value of the effective spring constant k for the web?

At what frequency would you expect the web to vibrate if an insect of mass 0.471g were trapped?

3) A pendulum has a period of 0.7421 seconds on Earth at sea level. (use g = 9.81 m/s^2) Calculate the change in the period of this pendulum if it were used at the top of Mt. Everest. (use g = 9.75 m/s^2)
