Question

Low-frequency vertical oscillations are one possible cause of motion sickness, with 0.30 hz having the strongest effect. your boat is bobbing in place at just the right frequency to cause you the maximum discomfort. the water wave that is bobbing the boat has crests that are 30 m apart. part a what is the speed of the waves? express your answer to two significant figures and include the appropriate units.

Answer 1

0.3 Hz is 0.3 waves per second.
We know that the water wave that is bobbing the boat has crests that are 30 m apart.
If there is a wave every 30 meters, then
30 meters/wave multiplied by 0.3 waves/second is 9 m/s
answer
the speed of the waves is 9 m/s
