The system is made up of the 1-m, 6.5-kg uniform rod AB and the two uniform disks (each of 0.19 m radius and 1.5 kg mass). If the system is released from rest when = 80°, when rod AB has just become horizontal, determine the coefficient C in the expression Cw² which is the kinetic energy of rod AB at this instant. Assume the disks roll without slipping. Your answer must include 2 places after the decimal point. Please pay attention: the numbers may change since they are randomized. AB' Take g= 9.81 m/s².
