To find the velocity of an object that has fallen 30 feet using the formula \( V = 64 \sqrt{h} \):
1. Substitute \( h = 30 \) into the formula:
\[
V = 64 \sqrt{30}
\]
2. Calculate \(\sqrt{30}\):
\[
\sqrt{30} \approx 5.477
\]
3. Multiply by 64:
\[
V = 64 \times 5.477 \approx 350.528
\]
4. Round the answer to the nearest hundredth:
\[
V \approx 350.53 \text{ feet per second}
\]
Therefore, the correct answer is not explicitly listed in the options given, but the closest to our calculated value is:
\[
350.54 \text{ feet per second}
\]
