Why do you need to know anything about the centripetal acceleration? The artificial gravity would not have to be the same as earth's gravity.Hootenanny said:HINT: To create the artificial gravitational force what must the centripetal acceleration of the space station be?

Indeed, I was wrong. This should be treated as a conservation of angular momentum problem. Good Catch Dan, apologies to chee.OlderDan said:Why do you need to know anything about the centripetal acceleration? The artificial gravity would not have to be the same as earth's gravity.
ok but how do i discern the what the masses are used for?? is the angular moment L = Iw ?Hootenanny said:Indeed, I was wrong. This should be treated as a conservation of angular momentum problem. Good Catch Dan, apologies to chee.
this is extremely clear...will try this when i get home later today! thanks and if have any probs check your PM...if you choose toOffice_Shredder said:You know what I is initally. You should be able to figure out what I is if everyone is in the center. You should also be able to figure out what I is if everyone is on the outer shell.
You know Iw is constant (angular momentum is constant), so put I when everyone is in the middle over I when everyone is on the outside, you get w when everyone is on the outside over w when everyone is inside
hey it's fine! no worriesHootenanny said:Indeed, I was wrong. This should be treated as a conservation of angular momentum problem. Good Catch Dan, apologies to chee.
