Hi gneill.
No, unfortunately, I can't. The type of collision was not specifically stated in the problem. However, even if the collision is inelastic, it is hard for me to imagine that most of the kinetic energy of the ball would be transferred into heat, sound, etc. Using the conservation of...
When I solved the problem using the conservation of angular momentum, I have got the correct result (ω = 0.006 rad/s). However, when I tried to find the answer using the conservation of energy the result was incorrect and I do not understand why.
