Two wheels of moment of inertia 9.9 kg.m and 4.6 kg.m are set in rotation with angular speed 5.1 rad/s and 9.4 rad/s, respectively When they are coupled face to face (as shown in the following figure) they rotate witha common angular speed co due to frictional forces, then what is the change in kinetic energy (0) of the wheels due to frictional forces? Before coupling After coupling Select one. a. 58.07 O b.-58.07 C-29.04 O d 29.04
