A 7-kg block is suspended by three identical springs, each with k = 200 N/m. The bottom of the block is attached to a dashpot that provides a damping force of F= 50|M N, where v is in m/s. At t = 0 s, the block is given an initial velocity upward of 0.6 m/s from its equilibrium position. (a) What is the natural frequency of the system? (b) Show whether this is an underdamped, a critically damped, or an overdamped system. (c) What is the frequency of the damped system? (d) What is the amplitude of the damped oscillation?

Question
Transcribed Image Text:A 7-kg block is suspended by three identical springs, each with k = 200 N/m. The
bottom of the block is attached to a dashpot that provides a damping force of F=
50|M N, where v is in m/s.
At t = 0 s, the block is given an initial velocity upward of 0.6 m/s from its equilibrium
position.
(a) What is the natural frequency of the system?
(b) Show whether this is an underdamped, a critically damped, or an overdamped
system.
(c) What is the frequency of the damped system?
(d) What is the amplitude of the damped oscillation?
