16.35 A pair of 10 cm radius, 2 kg disc flywheels with frictionless bearings are spinning at 1000 rads- and are supported at a distance d = 15 cm on either d d d d side of a universal bearing by a small diameter bar AB of mass M = 1kg and length 4d, as shown in Fig. 16-21. X B A (a) If a ball of mass m = 10g is dropped from a height h = 5 cm onto the tip A of the bar and rebounds upwards, give the components of the resulting angular momentum L of the flywheels and sketch the motion of the tip of Figure 16-21 the bar as seen from the +x direction. Also, give the angular velocity In of this motion and the radius r of the circle described by the tip once circular motion is attained. 16-6 (b) If the same ball instead were attached to the tip A, then what would be the angular velocity of precession Qp, neglecting nutation? What would be the angular momentum Lp and the rotational kinetic energy To associated with Op? How much potential energy AE is lost as the tip sinks below the xy-plane
