Q 3 Sol A thin and uniform rod of mass M and length L is held vertical on a floor with large friction The rod is released from rest so that it falls by rotating about its contact point with the floor without slipping Which of the following statement s is are correct when the rod makes an angle 60 with vertical g is the acceleration due to gravity A The radial acceleration of the rod s center of mass will be 38 B The angular speed of the rod will be C The angular acceleration of the rod will be Mg D The normal reaction force from the floor on the rod will be 16 A B D To find oo we apply COE 0 2L aCM radial 00 0 1 38 To find o we take torque about A L Mg sin 60 ML a So 3g sin 60 21 L 3g a sin 60 4 thongo ML Mg 1 cos 60 B 60E mg 00
