Re: classical physics - rod anchored to ground, rotational inertia
schweitzer, im taking the the 3rd too, gl.
both are wrong. im beginning to think it could be rotational...for the first...you cant take the hight of the center of mass cuz it just wants the tip of the rod and theyll be moving at different angular velocities. if the w=v/r. im thinking if you can scale that out then maybe.
the answers (3gl)^.5
and #2 was (55/2)* mr^2
