Answer:
the value of hi changes from 58 to 0:
h(t) = -4.9t^2 +19.8t
Step-by-step explanation:
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.
![h(t)=-4.9t^2+19.8t+0\\\\\boxed{h(t)=-4.9t^2+19.8t}](https://tex.z-dn.net/?f=h%28t%29%3D-4.9t%5E2%2B19.8t%2B0%5C%5C%5C%5C%5Cboxed%7Bh%28t%29%3D-4.9t%5E2%2B19.8t%7D)
