Asolid sphere of radius r is placed at a height of 30 cm on a 15° slope. it is released and rolls, without slipping, to the bottom. from what height should a circular hoop of radius r be released on the same slope in order to equal the sphere’s speed at the bottom?
b) can a circular hoop of different diameter be released froma height of 30 cm and match the sphere's speed at the bottom? if, so what is the diameter? if not, why not?
