2(. 15 points)A body of mass is m kg which is suspended by a spring of stiffness of 1000N/m and dashpot of damping constant 1000Ns/m. Vibration is excited by a harmonic force of amplitude m N and a frequency of m Hz. Calculate (Note: values of m equal to ID which is your class number).
(1) the amplitude of the displacement for the mass;
(2) the phase angle between the displacement and the excitation force.
