The pendulum is released from the 60° position and then strikes the initially stationary cylinder of mass m₂ when OA is vertical. Determine the maximum spring compression δ. Use the values m₁ = 3 kg, m₂ = 2 kg, OA = 0.8 m, e = 0.7, and k = 6 kN/m. Assume that the bar of the pendulum is light so that the mass m₁ is effectively concentrated at point A. The rubber cushion S stops the pendulum just after the collision is over. Neglect all friction.
