A light block hangs at rest from the end of a spring when it is pulled down 10 cm and released. Assume the block oscillates with an amplitude of 10 cm on either side of its rest position with a period of 1.5 s. Find a trigonometric function d(t) that gives the displacement of the block t seconds after it is released, where d(t) > 0 represents downward displacement.
