A water-skier is moving at a speed of 14.3 m/s. When she skis in the same direction as a traveling wave, she springs upward every 0.450 s because of the wave crests. When she skis in the direction opposite to that in which the wave moves, she springs upward every 0.342 s in response to the crests. The speed of the skier is greater than the speed of the wave. Determine (a) the speed and (b) the wavelength of the wave.
