A mass m is attached to both a spring (with given spring constant k) and a dashpot (with given damping constant c). The mass is set in motion with initial position X and initial velocity vo. Find the position function x(t) and determine whether the motion is overdamped, critically damped, or underdamped. If it is underdamped, write the position function in the form x(t)=C₁e Pt cos (w₁t-a₁). Also, find the undamped position function u(t) = Co cos (wot-α) that would result if the mass on the spring were set in motion with the same initial position and velocity, but with the dashpot disconnected (so c = 0). Finally, construct a figure that illustrates the effect of damping by comparing the graphs of x(t) and u(t). 1 m= 2, c = 6, k = 16, x0 = 6, V₁ = 0

Transcribed Image Text:A mass m is attached to both a spring (with given spring constant k) and a dashpot (with given damping constant c). The mass is set
in motion with initial position X and initial velocity vo. Find the position function x(t) and determine whether the motion
is overdamped, critically damped, or underdamped. If it is underdamped, write the position function in the form
x(t)=C₁e Pt cos (w₁t-a₁). Also, find the undamped position function u(t) = Co cos (wot-α) that would result if the mass on the
spring were set in motion with the same initial position and velocity, but with the dashpot disconnected (so c = 0). Finally, construct a
figure that illustrates the effect of damping by comparing the graphs of x(t) and u(t).
