1. The problem statement, all variables and given/known data You attach a mass M to a string and wind the string around the circumference of a wheel. The wheel has two hubs with radii R1 and R2 with R2 > R1. You perform two experiments. First you wind the string around the smaller radius wheel and allow the mass to fall a distance h. In the second experiment you wind the string around the larger radius wheel and allow the mass to fall a distance h. Rank the rotational kinetic energy Krot of the wheel for each experiment. 2. Relevant equations 1/2I(ω^2) 3. The attempt at a solution Basically I was thinking that ω is independent of the radius so they would be equal but then if I=m(r^2) and ω = v/r then I(ω^2)=1/2m(r^2)(v^2/r^2) and the r's cancel out giving us rotational kinetic energy = 1/2mv So would the rotational kinetic energies be equal or would 1 be larger than the other?
