Frictionless pivot (0) Block A swinging hammer is released from rest with 0 = 90 degrees before impacting the stationary block with a mass of 30 kg. The total mass of the hammer is 10.75 kg and its centre of gravity is 0.52 m from the pivot at O. The hammer's mass moment of inertia about point O is 4.3 kg.m2. The coefficient of restitution between the block and the hammer is 0.6. What is the angular acceleration (in rad/s2) of the swinging hammer just after it is released (0 = 90 degrees)? Write your answer to two decimal places.
