Khan academy 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 t=0t, equals, 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 cm −20 cmminus, 20, start text, space, c, m, end text (measured from the top of the spring). it first achieves that average height on the way up at t = 0.2 t=0.2t, equals, 0, point, 2 seconds, and then again every 2 22 seconds. the object's maximum and minimum heights are each 5 cm 5 cm5, start text, space, c, m, end text from its average height. find the formula of the trigonometric function that models the height h hh of the weight t tt seconds after fang started the stopwatch. define the function using radians.
