I got a conceptual doubt:Momentum(linear) conservation doesn't depend on conservation of kinetic energy.But,is the opposite true?Can kinetic energy be conserved without the conservation of momentum? Thanks!

Sorry daniel:) i had forgoten for a moment this deduction) which is so easy.Now,i`ve made it.I`m just tired of demonstrating every inertia possible (big homework!).Ya helped a lot! thank ya! :cool:

Daniel,i`m almost there.i just have one more doubt.Where the result dS=R^{2}\sin\vartheta \ d\vartheta \ d\varphi comes from?I won't bother you anymore;) thanks!

hey Daniel,thanks!But,i`m still confused about the choice of dm and the use of coordinates to use on the integrals.could you elaborate some more?(my professor wants things with so much detail! :cry: ).Once more,i thank you and wait for yer answer. Jason.

Hello,mates.i`,ve been struggling to demonstrate the procedure to calculate the rotational inertia of a hollow/empty sphere around an axe that passes through its diameter.Please,could you shed me some light or show me the procedure(Even show me any online papers on it)I`d be Glad.Please help...
