The 300-lb bell is at rest in the vertical position before it is struck by a 75-lb wooden post suspended from two equal-length ropes. If the post is released from rest at θ = 45°, determine the angular velocity of the bell and the velocity of the post immediately after the impact. The coefficient of restitution between the bell and the post is e = 0.6. The center of gravity of the bell is located at point G and its radius of gyration about G is k_G = 1.5 ft.
