A2/5 (10 marks) The impact hammer shown in Figure A2.5 consists of an 8-kg solid cylinder C and a 5-kg uniform slender rod AB with the dimensions shown. The hammer is released from rest when = 90 and strikes the 20-kg block D. which can slide along the smooth, horizontal surface without friction. 500 mm 100 mm B 150 mm C50 mm A D Figure A2.5 Determine the velocity of block D and the angular velocity of the hammer immediately after the impact. The coefficient of restitution between the hammer and the block is e = 0.6.
