A 1/2 kg mass is attached to a spring with 20 N/m. The damping constant for the system is 6 N-sec/m. If the mass is moved 12/5 m to the left of equilibrium and given an initial rightward velocity of 62/5 m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.

What is the equation of motion?
y(t)=

The damping factor is:

The quasiperiod is:

The quasifrequency is:

Answer #1

The quasi frequency is just the frequency at which the cosine and sine functions
appearing in the formula for y(t) oscillate. So it is 2 Hz

Hence, The quasi period is 2π/2
