A 1-kg mass is attached to a spring whose constant is 16 N/m, and the entire system is then submerged in a liquid
that imparts a damping force numerically equal to 10 times the instantaneous velocity. Determine the equation of
motion if the mass is initially released from a point 1 meter below the equilibrium positon with an upward velocity of
12m/s.
