Throwing a Stone (Refer to Example 9.) A stone is thrown downward with a velocity of 66 feet per sec- ond (45 miles per hour) from a bridge that is 120 feet above a river, as illustrated in the figure. (a) Write a formula s(1) that models the height of the stone after i seconds. (b) Does the stone hit the water within the first 2 seconds? Explain. 120 f
