A mass-spring system with damping consists of a 7-kg mass, a spring with spring constant 3 N/m, a frictional component with damping constant 2 N-sec/m, and an external force given by f(t) = 10 cos 10 N. Using a 10-12 resistor, construct an RLC series circuit that is the analog of this mechanical system in the sense that the two sys- tems are governed by the same differential equation.
