1. The problem statement, all variables and given/known data 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. 2. Relevant equations deltaK=Kfinal-Kinital kfinal=.5*i*w where i is the inertia i=.5*m*r^2 w=w0+at 3. 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?
