Q: What will happen when the SLINKY is released: (a) The bottom end will begin to accelerate upward as the entire SLINKY collapses, (b) The bottom end will begin to accelerate downward as the entire SLINKY collapses, or (c) The bottom end will remain instantaneously at rest as the SLINKY collapses? A: The bottom end will remain at rest until the entire SLINKY has collapsed, at which time it will begin to accelerate downward.
