Provide an appropriate response.The height of an object after t seconds is given by the equation h = -16t2 + 9t + 9. When , solving for t means finding the time when the object hits the ground. A student uses the quadratic formula and finds 2 solutions. One is negative and the other positive. Which solution makes sense? Which does not? Why?

What will be an ideal response?


The positive solution makes sense and the negative solution does not. The model represents time after the object is launched, and negative time does not make sense in this context.
