17) an object is launched from a platform 80ft above the ground, with an intitial velocity 16 fps. The height of the object, h, in t seconds can be modeled by the equation: h × t = -16t 2 + 64t + 80. When does the object hit the ground?
18) An object is launched from a height of 48ft above the ground, with an intitial velocity 32 fps. The height of the object, h, in t seconds can be modeled by the equation: h × t = -16t 2 + 32t + 48. When does the object hit the ground?
