SOLUTION: Suppose that a flare is launched upward with an initial velocity of 80 ft./sec. from a height 224 ft. Its height in feet h(t) after t second is given by h(t) = -16 t2 + 80 t + 224.

Question 1150849: Suppose that a flare is launched upward with an initial velocity of 80 ft./sec. from a height 224 ft. Its height in feet h(t) after t second is given by h(t) = -16 t2 + 80 t + 224. After how long will the flare reach the ground?

=================
When h(t) = -16t^2 + 80t + 224 = 0
