A spring-mass system that has a spring constant of 5.0 N/m is subject to a periodic restoring force of 0.015 N at a frequency that is very close to the natural resonance of the system. If the amplitude of the motion of the mass at this driving frequency is 3.0 cm, the quality factor, Q, is
A) zero.
B) 5.
C) 10.
D) 500.

Question

Quizplus · Accepted Answer

The quality factor, Q, is given by Q = (resonant frequency * amplitude) / (damping force). Given the amplitude and the periodic force, Q can be calculated to be approximately 10.
