What is the magnitude of the change in potential energy of the block-spring system when it travels from its lowest vertical position to its highest vertical position? - Correct 1/2k0(L1+L2)^2 The students conduct experiment 2 in which the same block is connected to the same spring on a horizontal surface. The spring is stretched a distance L2 beyond its natural length and released from rest, allowing the block-spring system to oscillate. Frictional forces are considered to be negligible. Which of the following claims is correct about how the period of oscillation for the block-spring system in experiment 2 compares with the period of oscillation for the system in experiment 1, and what evidence supports the claim? - Correct The periods of oscillation for experiment 2 and experiment 1 are the same, because the block and the spring used in both experiments are identical. A student is asked to perform experiment 1, but with a spring of an unknown spring constant. The student performs four trials of the experiment with blocks of different mass and collects the data that are shown in the table. How should the student graphically analyze the data in order to determine the spring constant of the spring? -
