Set

y = 192

and solve for t.

192 = -16t

^{2}+ 12t ⇒-16t

^{2}+ 12t - 192 = 0Note that the discriminant of this quadratic equation is negative, so there is no real solution to this problem. The object never reaches 192 ft. This is a very poor question, asking for what cannot be found. Was the question typed correctly?
