Homework: Section 13.8 If an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its height h after t seconds is given by the equation h = −16t 2 +vt+s, where h is in feet. If the object is propelled from a height of 8 feet with an initial velocity of 96 feet per second, its height h is given by the equation h = −16t 2 +96+8. After how many seconds is the height 116 feet? Using the equation h = −16t 2 +vt+s, substitute the known values for h, v, and s: h = 116, v = 96, and s = 8. 116 = −16t 2 + 96 + 8
Since the equation is quadratic, I
