A wheel of radius R and mass m is mounted 1. All are true. on a frictionless, horizontal axle as shown in the figure. A light cord wrapped around the 2. A and C only wheel supports an object of mass M; the weight is released from rest at the level of A. 3. None is true. R 4. A and B only 5. C only 6. A only 07. B and C only M 8. B only BY Which of the quantities A. Sum of the angular momentum of the wheel about its center of mass and that of the falling weight about the wheel's center of mass; B. Kinetic energy of the wheel plus kinetic energy of the falling weight plus the po- tential energy of the falling weight; and C. Potential energy of the wheel; are constant during the fall? his
