## 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
