A water-skier is moving at a speed of 10.6 m/s. When she skis in the same direction as a traveling wave, she springs upward every 0.539 s because of the wave crests. When she skis in the direction opposite to that in which the wave moves, she springs upward every 0.427 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. (a) Number Units (b) Number Units
