An object hangs from a spring at a stationary rest position 9 meters above the ground. The object is pulled 3 m downward and released. The object begins to oscillate (move up and down), taking 4 seconds to first return back to the stationary rest position before continuing upwards in its movement. a) Graph the motion of the object over 2 full periods. b) Write an equation for the motion of this object where h(t) represents the height of the object and t represents the time in seconds. c) How far is the object from its rest position 1.5 seconds after release? d) When is the NEXT time that the object will be at this point again?
