Question

Ocean waves are traveling to the east at 4.9 m/s with a distance of 23 m between crests. (b) With what frequency do the waves hit the front of a boat when the boat is moving westward at 1.1 m/s

Answer 1

0.26086 Hz

Step-by-step explanation:

solution:

The relative speed of the wave is:

v = 4.9+1.1 = 6 m/s

the frequency is:

f = v/λ

= 6/23

= 0.26086 Hz
