## Homework Statement

Hi I know my picture has 2 problems, but lets just focus on the first problem parts a and b.

So for part a it ask for the final frequency after the ant landed, and part b is the kinetic energy difference. Basically the

ant=.01kg, diameter of cylinder is .115m,

the weight of cylinder is .03kg,

and its rotating at 300 rev/min.

## Homework Equations

[/B]

deltaK=Kfinal-Kinital

kfinal=.5*i*w where i is the inertia

i=.5*m*r^2

w=w0+at

## The Attempt at a Solution

For part a I used the the rotational equation formulas, Im not sire if i picked the correct one though. For part b, its based on part a, basically find the kinital and final with the mass changing from .030g t0 .040 cause the ant has its own weight. Part b I understand its jsut part a I am dont really know where to start?
