Two identical masses are in a hemispherical bowl of radius R. One block is sitting at the bottom and the other is at the top. The top block is released from rest and they collide.
(a) If they stick together, how high will they rise above the bottom of the bowl?
(b) If they do not stick but rather have a perfectly elastic collision, how high will each of them rise?
