A stick is resting on a concrete step with 1/7 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 theta = 62.1° with respect to the
horizontal, as shown in the figure.
Use g = 9.81 m/s².
If the mass of each bug is 3.26 times the mass of the stick and
the stick is 11.5 cm long, what is the magnitude a of the
angular acceleration of the stick at the instant shown?
