A 56.0 kg bungee jumper jumps off a bridge and undergoes simple harmonic motion. If the period of oscillation is 11.2 s, what is the spring constant of the bungee cord, assuming it has negligible mass compared to that of the jumper?
 
  A) 17.6 N/m
  B) 21.1 N/m
  C) 28.2 N/m

Question 2

An object of mass 8.0 kg is attached to an ideal massless spring and allowed to hang in the Earth's gravitational field.

  A) 2.6 Hz
  B) 0.0045 Hz
  C) 0.67 Hz
  D) 2.1 Hz
