Please solve this problem by showing the manual calculation and choose the correct answer(SUBJECT: mechanical vibrations)

For a single degree of system mass is 20kg stiffness=6.25kN/m damping coefficient 20Ns/m.Initial displacement at t=0 is zero and initial velocity is 150m/s obtain the equation of motion and find the displacement at 2seconds

Sketch frequency response of the system from part (a) in the form of Bode plot as accurately as you can.

Consider the damped mass-spring system for mass of 1.5 kg, spring constant 10 N/m, damping 3 kg/s and an oscillating force 4.7 cos(@t) Newtons. That is, 1.5x" + 3x' + 10x = 4.7 cos(@t). What positive angular frequency o leads to maximum practical resonance? W = help (numbers) What is the maximum displacement of the mass in the steady state solution when the we are at practical resonance: C(@) = help
