A block moving on the end of a spring with a force constant ? = 2.5 ?⁄? is acted on by a damping force ?? = −???. (a) If the constant b has the value 0.9 kg/s, what is the frequency of oscillation of the block? (b) For what value of b will the motion be critically damped? (c) Draw brief sketches and explain the difference between underdamped, critically damped and overdamped oscillations.
