Answer:
s = 28.09 m/s
Step-by-step explanation:
Given that,
The equation that gives the height of the largest ocean waves when the wind speed is s knots is given by :

We need to find the wind speed if the largest waves are 15 feet high.
Put h = 15 feet in the above equation as follows :

So, the speed of the wind is 28.09 m/s.
