the dolphin’s height at any given time, t. What is the maximum height the dolphin jumps?
~~~~~~~~~~~~~~~~

I made quick calculations on the problem.

They showed me that the time jumping in the air ABOVE the water surface is 5 seconds;

the time to reach the maximum height is 2.5 seconds and the maximum height is 100 feet.

These results show that the input data is ABSOLUTELY UNREALISTIC --- a dolphin is not a bird --- it is totally different creation.

THEREFORE, the posed problem is a FAKE and has no right to exist.
