A 6lb wieght can stretch a spring 6 inches. Suppose the weight is pulled 4 inches past the equilibrium point and released from rest. The initial equation is y(t)=1/3*cos(8t)+0*sin(8t) Suppose that a damping force given in pounds numerically by 1.5 times the instantaneous velocity in feet per second acts on the 6lb weight. Find the position x of the weight as a funtion of time.
