  A)
 
  Inductor: zero energy. Capacitor: zero energy
  B)
 
  Inductor: Half of the maximum energy. Capacitor: Half of the maximum energy
  C)
 
  Inductor: maximum energy. Capacitor: zero energy
  D)
 
  Inductor: zero energy. Capacitor: maximum energy
  E)
 
  Inductor: maximum energy. Capacitor: maximum energy

Question 2

A spring with a force constant of 2.00 N/m is attached to a mass of 75.0 g. The system has a small amount of damping.

  A)
 
  0.00693 Ns/m
  B)
 
  0.0462 Ns/m
  C)
 
  0.00762 Ns/m
  D)
 
  0.0100 Ns/m
  E)
 
  0.00857 Ns/m
