Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_71

4/71 The end of a pile of loose-link chain of mass \(\rho\) per unit length is being pulled horizontally along the surface by a constant force \(P\). If the coefficient of kinetic friction between the chain and the surface is \(\mu_k\), determine the acceleration \(a\) of the chain in terms of \(x\) and \(\dot{x}\).
