A mass m = 4 is attached to both a spring with spring constant

A mass Tn = 4 iS unached to both a spring with spring constant k 257 and a dash-pot with damping constant c The mass is started in motion with initial position = 2 and initial velocity vo = 2 Determine the position function :r(t) Note that, in this problem, the motion of the spring is underdamped, therefore the solution can be written in the form Cre Picos(u.'lt m). Determine Cl, Oland p. 01 Consider the Which of the followi" (assume O at < 27) A value problem a:" -F 2.T' .50;r 2cos(6t), u simplest algebraic form of the steady-state solution of the problem? (check one) . Atcos(6t) + Bcos(6t) = At sin(6t) 4 B sin(6t) . Acos(6t) + B sin((jt) ODY . Acos(6t) + B sin(6t) + Ctcos(6t) + Dt sin(6t) C) E. All of the above are solutions Enter the steady-periodic solution of the Initial value problem:
