• an object is attached by a string to the end of a spring. fang throws the object upwards and starts a stopwatch at \[t=0\] seconds. the object starts oscillating vertically in a periodic way that can be modeled by a trigonometric function. the object's average height is \[-20\text{ cm}\] (measured from the top of the spring). it first achieves that average height on the way up at \[t=0.2\] seconds, and then again every \[2\] seconds. the object's maximum and minimum heights are each \[5\text{ cm}\] from its average height. find the formula of the trigonometric function that models the height \[h\] of the weight \[t\] seconds after fang started the stopwatch. define the function using radians.
