Question: A 2.00-kg block hangs from a rubber cord, being supported so that the cord is not stretched. The unstretched length of the cord is 0.500

A 2.00-kg block hangs from a rubber cord, being supported so that the cord is not stretched. The unstretched length of the cord is 0.500 m, and its mass is 5.00 g. The “spring constant” for the cord is 100 N/m. The block is released and stops at the lowest point.
(a) Determine the tension in the cord 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.
