Solved: Suppose the mass m in the spring/mass system in
Chapter 5, Problem 5.1.149(choose chapter or problem)
Suppose the mass m in the spring/mass system in slides over a dry surface whose coefficien of sliding friction is . If the retarding force of kinetic friction has the constant magnitude where mg is the weight of the mass, and acts opposite to the direction of motion, then it is known as coulomb friction. By using the signum function determine a piecewise-defined differential equation for the displacement of the damped sliding mass
