Question

A stick is resting on a concrete step with 1 3 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 θ = 41.3 ∘ 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 of the angular acceleration α of the stick at the instant shown? A square step with a straight stick of length L balanced on the edge of the step. The stick makes an angle theta above the step surface. A ladybug rests on either end of the stick.

α = rad / s^2
