- 1/2Iw^2 = mgh
(1/2(1/12Ml^2+(1/2)^2Mw^2)/mg = h = 0.157
(Note: the stick weight is 0.4kg not 1.0kg)
Im not a native English speaker. So please excuse my bad english.
I had this on my exam, and Ím really unsure what the answer to this is. Ím suppose to calculate the hight and angle of the swing Of this stick after a “stuck together” collition. But I’m really unsure if I should calculate a new masscenter or is it enough to just calculate the moment of inertia?
It confuses me. Since I think if I tilt the stick 30degrees before the crash, the gravity of the tip is the same? So it will stand still if I tilt it 30degrees? It feels unlogical, but I am not able to make a proper argument to explain my feeling. I would be great with either an answer or explanation what would be right/wrong to think...
