A spring with a force constant of 1.50 N/m is attached to a mass of 120 g. The system has a damping constant of 0.0180 Ns/m. How long does it take the amplitude of the oscillations to decrease from 10.0 mm to 5.00 mm?
 
  A) 12.5 s
  B) 10.0 s
  C) 6.25 s
  D) 4.62 s
  E) 9.24 s

Question 2

An underdamped spring-mass system consists of a spring with a force constant of 2.00 N/m and a mass of 550 g. It is observed that the oscillations decrease in magnitude by 10.0 every 360 s. What is the value of the damping constant for the system?
 
  A) 3.22  10-4 Ns/m
  B) 2.16  10-4 Ns/m
  C) 11.7  10-4 Ns/m
  D) 5.85  10-4 Ns/m
  E) 8.95  10-4 Ns/m
