STATEMENT: In an experiment, an ideal spring is fixed vertically to the ceiling of the laboratory and has a natural length of 100 cm. A particle is then attached to the lower end of the spring and released from rest. Using a sensor, the velocity of this particle was measured, and the graph of its kinetic energy \(E_c\) as a function of the length \(L\) of the spring was plotted, as illustrated below.
