Part A A 2.00 kg block hangs from a rubber cord. The block is supported so that the cord is not stretched. The unstretched length of the cord is 0.465 m, and its mass is 5.11 g. The "spring constant" for the cord is 113 N/m. The block is released; we'll consider what happens at the moment the block is at its lowest point. 4a Determine the tension in the cord when the block is at the lowest point (in newtons). • Part B What is the length of the cord in this "stretched" position (in meters)? Part C 4c Calculate the speed of a transverse wave (in m/s) in the cord if the block is held in this lowest position.
