Assuming there are no frictional losses, which of the following statements could account for this observation? a) There is not enough information to answer the question. b) The other end of the spring is unattached (ie it is a free-end) c) The spring is attached to a second spring of a higher density and slower speed. d) The spring is attached to a second spring of lower density and faster speed. e) The other end of the spring is attached to a fixed-end.
