Answer:
The maximum height of the water balloon occurs at x = 0.
The water balloon is in the air for 2 s.
The maximum height of the water balloon is 64 ft.
Step-by-step explanation:
The water balloon rises above 64 ft before falling toward the ground.
I'm confused since it does start at a height of 64, but I think it meant that it started lower then went up, so I would say that wouldn't be true.
The water balloon hits the ground in 64 s
it hits the ground at 2 seconds
A = v/t Multiply both sides by t
A(t) = v Divide both sides by A
t = v / A
