Homework Statement
A water-skier is moving at a speed of 13.3 m/s. When she skis in the same direction as a traveling wave, she springs upward every 6.2 s because of the wave crests. When she skis in the direction opposite to the direction in which the wave moves, she springs upward every 3.5 s in response to the crests. The speed of the skier is greater than the speed of the wave.
Determine Speed of the wave
Determine Wavelength of wave
Homework Equations
v=f*(lamda)
v=d*t
f= 1/t
The Attempt at a Solution
I know that in 6.2 seconds that he is going from crest to crest of a wave. Which means in 6.2 seconds he is completing one cycle. 6.2 seconds is the Period of the wave. His skier moves at 13.3.
That means that the distance he covers is 6.2*13.3 = 82.46m
This 82.46 m is the distance between two crests or equal to one wavelength.
I get stuck here and I get marked wrong by the online HW website. Plz help
