A water rocket is launched from the ground, reaching the maximum height of 64 feet before landing on the ground 4 seconds later.
Which of the following quadratic equations can be used to model the relationship between the height of the rocket, h, and the time, t?
h(t)=16t2+64t
h(t)=−16t2+64t
h(t)=16t2−64t
h(t)=−16t2−64t
