An object is launched vertically upward from a 25 foot platform and is modeled by the function s(t) = - 16t ^ 2 + 11t + 25 The object will fall back to the ground after Select one seconds because Select one cannot be a solution.

The object will fall back to the ground after approximately 1.72 seconds because when t = 1.72, s(1.72) = 0, which means the object has fallen back to the ground.
