Extracted text: A mass of 300g hangs in a spring with a spring stiffness of 40 N/m (same situation as in Exercise 4.6). The mass is connected to the spring with a weightless cord, the rigidity of the cord can be considered infinite, ie it is so large that it does not affect the rigidity of the system. We start with a situation where the spring is not loaded and the weight is placed at the end of the spring. So the weight is ground free so that it falls from a height equal to the length of the string before it starts to act on the spring. 0 cm, 6.0 cm, 12 cm, 24 cm. That is, for situations when the length of the cord is 0 cm, 6.0 cm, 12 cm and 24 cm.
