Again finding the zeros 
-16t^2 +96t 
i found it to be (0,0) (6,0) i am sure you know how to find them you just wanted to make sure

Thank you so much!

yes as mentioned before the ground is mapped by y = 0
So you solve for 0 and the solutions (providing they make sense) indicates the times you rocket is on the ground (first for lift off, second for fall).
