Physics

A stick is resting on a concrete step with 1/7 of its lengthhanging over the edge. A single ladybug lands on the end of thestick hanging over the edge, and the stick begins to tip. A momentlater, a second, identical ladybug lands on the other end of thestick, which results in the stick coming momentarily to rest 36.1°from the horizontal. If the mass of each bug is 2.75 times the massof the stick and the stick is 18.7 cm long, what is the magnitudeof the angular acceleration of the stick at the instantshown?(answer in rad/s^2)

at the moment the stick comes to rest at theta 361o from horizontalAngular acceleration net torque moment of inertiaHere we have to add up thetorques due to the bugs and the stick and add up the moments ofinertia due to all three alsoLet L be the sticks length andlet m be the sticks massThen 275m is each bugsmassAnd    See Answer
