The speed of the surfer is 4ft/s
Given,
Average wavelength(W) = 40ft
T=10s
So, Speed = W/T=40/10=4ft/s
<h3>Wavelength</h3>
The distance over which a periodic wave's shape repeats is known as the wavelength. It is the separation between neighboring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both traveling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.

Answer:
2.8125 meters
Explanation:
I will assume 7.5 m/s
When the Kinetic Energy is entirely converted to Potential energy the max height will have been reached
KE = PE
1/2 m v^2 = mgh divide by m
1/2 v^2 = gh looking for h so divide both sides by
1/2 v^2 / g = h sub in the values using g = 10 m/s^2
1/2 ( 7.5 )^2 / 10 = 2.8125 m
Answerspeed = 0.0333333 meters per second
= 0.0333333 m/s
Explanation:
i'm not 100% sure but i think that's the answer
