Homework Statement
A jetskier is moving at 9.8 m/s in the direction in which the waves on a lake are moving. Each time he passes over a crest, he feels a bump. The bumping frequency is 1.1 Hz, and the crests are separated by 5.6 m. What is the wave speed?
Homework Equations
velocity = frequency * wavelength
The Attempt at a Solution
I thought to multiply the 1.1 Hz which is the frequency by the 5.6 which is the wavelength to get a velocity...I got 6.16 m/s then I was not sure what to do next...should I add it to the jetskier's velocity 9.8 m/s because they are going in the same direction? What should I do?
