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