Homework Statement
A hollow sphere of mass M and radius R (I = 2MR2 /3) is released from rest at height h and rolls down a curved surface without slipping until it reaches the lowest point, O..
The curve to the right of O is frictionless. If the sphere continues past point O, what vertical height will it reach?
(In the diagram, the curve looks like a semi circle)
Homework Equations
KEr = 1/2 M W2
KEl = 1/2MV2
The Attempt at a Solution
According to my knowledge, if its frictionless and energy is conserved it should reach the same high.
mgh = 1/2 M W2 + 1/2MV2
