Question:

A block of mass M hangs from a rubber cord. The block is supported so that the cord is not stretched. The unstretched length of the cord is L0 and its mass is m, much less than M. The “spring constant” for the cord is k. The block is released and stops at the lowest point.
(a) Determine the tension in the string when the block is at this lowest point.
(b) What is the length of the cord in this “stretched” position?
(c) Find the speed of a transverse wave in the cord if the block is held in this lowest position.
