Answer:
1. 36
2. Second
Explanation:
- For the first ball, we can see the given function:

![=-16[t^(2) -3t+(3/2)^(2)-(3/2)^(2) ]](https://img.qammunity.org/2022/formulas/mathematics/high-school/d1fiuxv3193sglbib0ld4akxnptzay75p0.png)


So the vertex is (
, 36), it means when the ball was hit by the
seconds, it arrived at the highest height of 36 feet.
- For the second ball, we can see the given graph: the vertex is (2,64), it means when the ball was hit by the 2 seconds, it arrived at the highest height of 64 feet.
- Compare to the two heights, 36 (first ball) is less than 64 (second ball), so the second ball went higher.
