Final answer:
The balloon was released from a height of 2 units.
Step-by-step explanation:
The height of the water balloon at any given time can be determined using the formula h(t) = -5t² + 40t + 2. To find the height from which the balloon was released, we need to find the initial height, which is the value of h(t) when t = 0. Plugging in t = 0 into the equation, we get:
h(0) = -5(0)² + 40(0) + 2
h(0) = 2
Therefore, the balloon was released from a height of 2 units.
