A mass m moves along the x-axis subject to an attractive force given by 17β2mx/2 and retarding force given by 3βmv, where x is the distance from the origin and β is a constant. A driving force given by mAcosωt, where A is a constant is applied to the particle along the x-axis. Determine value of ω results in steady state oscillations about the origin with maximum amplitude? Find what is the max amplitude?
