Solve the problem.A spring with a spring constant k of 18 pounds per foot is loaded with a 16-pound weight and allowed to reach equilibrium. It is then displaced 2 feet downward and released. If the weight experiences a retarding force in pounds equal to 10 times the velocity, find the equation of motion.
