A 1-kilogram mass is attached to a spring whose constant is 18N/m, and the entire system is then submerged in a
liquid that imparts a damping force numerically equal to11 timesthe instantaneous velocity. Determine the equations of motion if the following is true.
(a) the mass is initially released from rest from a point 1 meter below the equilibrium position
