A stick is resting on a concrete step with of its total length L hanging over the edge. A single ladybug lands on the end of the stick hanging over the edge, and the stick begins to tip. A moment later, a second, identical ladybug lands on the other end of the stick, which results in the stick coming momentarily to rest at 0 = 46.5° with respect to the horizontal, as shown in the figure. If the mass of each bug is 2.92 times the mass of the stick and the stick is 18.7 cm long, what is the magnitude a of the angular acceleration of the stick at the instant shown? Use g = 9.81 m/s? rad/s? Figure is not to scale. Two thin disks are attached as shown in the image. The angle 0 = 55.7°, and the masses and radii of the disks are listed in the table. B Disk Radius (cm) Mass (kg) A 16.8 0.791 B 9.70 0.337 A What is the moment of inertia of this composite object about an axis perpendicular to the screen, through point P? moment of inertia: kg-m²
