Homework Statement
Basically the problem is asking me to find the rate of rotation of a space station that is in the shape of a wheel 120m in diameter, and rotates to provide an "artificial gravity" of 3.00 m/s.
And it has to be in rev/min.
Homework Equations
The only equation so far I that has to deal with this is the one
ac = [tex]v^2/r[/tex]
The Attempt at a Solution
it seemed pretty simple and straightforward. So first i took the gravity which is of course the acceleration in this case. And then set it equal to v^2/60.
Then i solved for v.
After solving for v I used that to see how long one revolution is by using the equation, v=d/t. Substituting in the 120 m for d.
So I send up with a time in sec for every 120m revolution.
Then I converted from sec to min by divinding by 60.
I still can't get the answer in the book.
