Homework Statement
if i have 2 spheres, one big sphere and one small (R>r),
both are rolling from the same point down the way.
at the end of the way, which sphere would have bigger speed?
i thought the smaller sphere would have, since,
angular acceleration = (f * r ) / I = f / (0.4MR)
now if R>r shouldn't the acceleration be smaller as well?
