3) (Student Spinning on Stool) A student sits spinning on a stool at initial angular velocity angular velocity w, = 4.00 Hz, initially with arms rigidly outstretched, holding two identical m= 2.00 kg weights (one in left hand and one in the right hand) at distance r = 0.600m from the student's axis of rotation. The student's moment of inertia (without including the contribution of the two weights) is I = 4.00 kg m². Assume that the contribution of the...
Consider the pendulum bob shown. The bob is
