Help please.

[1 point} A mass m = 4 kg is attached to both a springwith spring constant k = 25'? me and a dashpot with damping constantc = 4 N - aim. The mass is started in motion with initial position 3o = 5 m and initial velocity "o = 9 Info . Determine the position function t] in meters. Sit) = A Note that, in this problem, the motion ofthe spring is underdamped, therefore the solution can be written in the form m3} = Ole\"caslylt 01}. Determine (ILL-:1 ,aland 11 Cl = {#1 = // on = [assume 0 3 a1 4:: 2w} 3: = a Graph the function t] together with the "amplitude envelope" curves 3 = 01e'1" and :I: = Ole1". Now assume the mass is set in motion with the same initial position and velocity, but with the dashpot disconnected { so .3 = D]. Solve the resulting differential equation to nd the position function \"('3)- In this case the position function u[t) can be written as n(t} = Cucoatunt an]. Determine Co. on] and an.
