Minimum Vo for a hoop to get to the top

[QUOTE="Cleo James, post: 5503118, member: 596913"] Well, conservation of momentum: m1v1 + m2v2 = (m1+m2)v3 But this is if the object experiences inelastic collision, I don't know how to apply it when the other object is just a small bump. Conservation of angular momentum: Iw1= Iw2 since the hoop will rotate about the edge of the bump during collision, parallel axis theorem: mr^2 w1= 2mr^2 w2 w1= 2w2 At this time I can't seem to figure out what to do afterwards.
