Ap Physics 1 Unit 6 Progress Check |22 Questions| With Correct Answers.

A block of mass M on a horizontal surface is attached to a horizontal spring of negligible mass. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the block is pulled to a position beyond the spring's natural length and released from rest, the block experiences simple harmonic motion. A graph of the force exerted on the spring as a function of the block's position is shown. A student collects data such that the force that the spring exerts on the block for every 0.25s is plotted on the graph that is shown. Which two of the following claims is correct about the block-spring system during the time in which data were collected? Select two answers. {Ans: The block has its maximum acceleration at all times 0.5n, where n is a zero or a whole number. B The block has maximum spring potential energy at all times 0.5n, where n is a zero or a whole number.}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
