1. An object suspended from a spring is oscillating up and down. It started this periodic motion when it was pulled down by 16cm from its rest position of 80cm above the floor and released. It returned to its rest position after 0.5 seconds and then continued upwards reaching its maximum height. a) Model this motion with a graph. b) Model its motion with the equation.
