Scrat's tongue is stuck to the ice, and he is hanging vertically. He starts swinging from side to side.
A. If momentum and angular momentum and energy are supposed to be conserved, then how does he start swinging?
B. If the contact forces between his tongue and the ice break down at a tension of T, how high can he swing before his tongue breaks from the ice?
