57. Two spring-block systems are placed in a viscous environment independently. The
viscous forces experienced by the blocks is approximately linearly proportional to
the speed of blocks. Due to the damping effect, both spring-block systems exhibit
underdamped oscillating bchavior. The shape of blocks of the two systems is the
same, but the mass and spring constant of the 1st and the 2nd system are (1 kg, 1
Nim) and (1.2 kg, 0.9 N/m), respectively. Initially, both blocks are at rest and are
released 5 cm away from their equilibrium positions. Which of the following
statements is true?
(A) It takes a longer time for the block in the 2nd system to finally come to rest.
(B) It is not possible for these two systems to both exhibit underdamped
behavior.
(C) Both blocks move towards the equilibrium position and then stop at the
equilibrium position.
(D) In the very beginning, the oscillation frequency is larger for the 1st system.
(E) In the very beginning, the oscillation frequency is larger for the 2nd system.
