Homework Statement
[itex]m[/itex]mouse [itex]= 0.06kg[/itex]
[itex]r = 0.3m[/itex]
[itex]\omega = 0.05 rad / s[/itex]
Suppose angular speed does not change.
What is the work needed for the mouse to go to the center.
Homework Equations
[itex]I[/itex][itex]o[/itex][itex]\omega[/itex][itex]o[/itex] = [itex]I[/itex][itex]f[/itex][itex]\omega[/itex][itex]f[/itex]
The Attempt at a Solution
If [itex]\omega[/itex] doesn't change ,then how can I use the above equation.
Since [itex]I[/itex] of mouse would be equal to [itex]mr^2[/itex] then [itex]\omega[/itex] would change. I am stuck here. Oh, and it's not a homework, it's a problem that I was stuck at some time ago. Thanks for any help
