A brick is attached to a horizontal spring and is able to slide back and forth. The mass of the brick is m= 2 kg., the spring constant is k = 40 N./m., and friction provides a resistive force equal (in N.) to c= 16 times the velocity of the brick (in m./sec.). a) Formulate a differential equation that models this problem, using 1 = time (in secs.) and x(t) = displacement (to the right of the equilibrium position, in...
