Suppose waves move in the open ocean at a speed of v1
= 4.5 m/s, at an angle of ?1 = 41o to the
normal to the shore, see figure. At some distance from the shore,
the ocean floor rises and the speed of the waves drops from
v1 to v2 = 3.0 m/s. At what new angle to the
normal do the waves now approach the shore (in degrees)?

Suppose three surfers are floating in the ocean at different distances from the shore as waves travel toward the shore. Tom is out 20 m, Susan is out 50 m, and Ted is out 60 m. Tom and Ted observe that they are always in sync with each other, that is, Tom and Ted move up and down together. They observe that Susan is always out-of-sync with both Ted and Tom. What is the wavelength of the ocean waves coming...

4. Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable, but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 750 km and traveled a distance of 3700 km in 5.3 h. (a) What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about...

Review Constants Periodic Table A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.10 s for the boat to travel from its highest point to its lowest, a total distance of 0 670 m. The...

A dolphin (Dolphin A) is swimming under the ocean at a speed of 4.87 m/s, emitting sonar sound wave at a frequency of 1222 Hz. The speed of sound waves under the ocean is 5518.8 km/h. Another dolphin (Dolphin B), located away is such that the two dolphins move towards each other. If Dolphin B is moving at 7.31 m/s, calculate the frequency that would be detected by a receiver attached to Dolphin B as the two fish swim towards...

Review | Constants Part A A water wave is a shallow-water wave if the water depth d is less than ~ 1/10. It is shown in hydrodynamics that the speed of a shallow-water wave is v= Vgd, so waves slow down as they move into shallower water. Ocean waves, with wavelengths of typically 110 m , are shallow-water waves when the water depth is less than 11 m. Consider a beach where the depth increases linearly with distance from the...

A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height, H of 31.0 m above sea level, directed at an angle θ above the horizontal with an unknown speed v0 A V The projectile remains in flight for 6.00 seconds and travels a horizontal distance D of 153.0 m. Assuming that air friction can be neglected, calculate the value of the angle θ Submit Answer...
