Science-8G As shown in Figure 1 below, one end of a spring is attached to a platfom on a smoothhorizontal surface, and the other end is fixed in place. A person is standing on the platfom.The platfom is pushed to the left, compressing the spring to less than its natural length, andis gently released. The platform begins undergoing simple harmonic motion with a periodof T. Let us denote the displacement of the platform from its position when the spring isat its natural length as I, where its positive direction is indicated by the anow in Figure 1(pointing to the right).
