The pendulum is released from the $60$ position and then strikes the initially stationary cylinder of mass me when OA is vertical. Determine the maximum spring compression $8.$ Use the values

m$1=3$ kg$,$ m$2=2$ kg$,$ OA $=0\mathrm{.}8$ m$,$ e $=0\mathrm{.}7,$ and

k $=6$ kN$/$m$.$ Assume that the bar of the pendulum

is light so that the mass m$,$ is effectively concentrated at point A$.$ The rubber cushion S stops the pendulum just after the collision is over. Neglect all friction.
