SHM question

  1. May 11, 2003 #1
    In a harbour, the time between successive high tides is 10 hours. On a day when the height of high tide above low tide is 8.0m, find
    (i) the angular frequency of the tides;
    (ii) the time interval within a cycle during which the sea-water is more than 5.0m above the low tide;
    (iii) the rate at which the tide is rising or falling when the sea-water is 5.0m above the low tide.

    Pls help me solve this problem, thanks!

    Hi Chense, and welcome to PF.

    We will be happy to help you with your homework, but first we would like to see how you started and where you got stuck.

    Just above your post is one titled "Sticky- Read before posting".
    Did you read it before posting?

    The critical part is:
    "Please, for your own sake, try your homework before you come here, and show us where you got stuck. Speaking for myself, I already know that I know how to do your problem. Me doing it for you accomplishes nothing."

    Yeah, the problem is pretty simple. What class is this for, and is it college or HS?
