I Review A student rotates on a frictionless piano stool with Part A his arms outstretched, a heavy weight in each hand. Suddenly he lets go of the weights, and they fall to the floor. As a result, does the student's angular speed increase, decrease, or stay the same? O stay the same O increase decrease Submit Request Answer Part B Choose the best explanation from among the following: The loss of angular momentum when the weights are dropped causes the student to rotate more slowly. O The student's moment of inertia is decreased by dropping the weights. Dropping the weights exerts no torque on the student, but the floor exerts a torque on the weights when they land.

M,R A dumbbell with mass 3M, radius R, and moment of inertia - MR2 is on an 3M incline of angle 0. There is sufficient friction on the incline so that the dumbbell rolls without slipping. The dumbbell is connected by a massless cord passing over a pulley of mass M and radius R (I = ½MR²) to a hanging mass M as shown below. The system starts from rest. M Draw free-body diagrams for the dumbbell (including one for torques), the pulley, and the (а) hanging mass, noting the coordinates used and the positive direction for torque, if applicable. Write down the translational and/or rotational forms of Newton's Second Law for the (b) three objects in the system. What is the acceleration of the system?
