Question 628226: I have a test that is coming up this Sunday and I need to know how to solve these type of Radical word problems. Can someone please help me with these questions and scenarios?
Note: For any decimal answers, please round to two decimal places.
The speed of a tsunami approaching land depends on the depth of the water the tsunami is in. So, the speed of the tsunami changes as is approaches the shore. The speed (in meters per second) of a tsunami in water that is d meters deep is given by s=3.13 square root d.
PROBLEM SHOW YOUR SOLUTIONS HERE
1. Solve this equation for d
2. By looking at the equation, would you expect tsunamis to travel faster or slower as they get closer to the shore (in shallower water)?

3. Find the speed of a tsunami in a depth of 500 m

4. Find the speed of a tsunami in a depth of 100 m
5. Do the answers to problems 3 and 4 confirm your expectation from problem 2? Do Tsunami’s travel faster or slower in shallow water?

Hi,

s+=3.13sqrt%28d%29 

1. Solve this equation for d = %28s%2F3.13%29%5E2

2. By looking at the equation s+=3.13sqrt%28d%29 , would you expect tsunamis to travel faster or slower 

as they get closer to the shore (in shallower water)? slower



 3. Find the speed of a tsunami in a depth of 500 m s+=3.13sqrt%28500%29=+70mps



 4. Find the speed of a tsunami in a depth of 100 m s+=3.13sqrt%28100%29=+31.3mps

5. Do the answers to problems 3 and 4 confirm your expectation from problem 2? Yes

 Do Tsunami’s travel faster or slower in shallow water?
