Homework Help: Speed of SHM

  1. Sep 29, 2010 #1
    1. The problem statement, all variables and given/known data

    A proud deep-sea fisherman hangs a 65.0- fish from an ideal spring having negligible mass. The fish stretches the spring 0.120 . k= 5310N/m

    Im suppose to find the maximum speed it will reach.

    2. Relevant equations



    3. The attempt at a solution

    I heard that velocity of vertical SHM can be found by wA, but i dont know what w is. So im having hard time solving this question.

    I don't understand what this problem is asking.

    As I read this, it seems that the fish is in its equilibrium position and is therefore static.

    Is the spring constant given or did you calculate it?

    What is the maximum speed it will reach? is the question. I found the spring constant, but i dont know if it helps solving the question

    I understand the question. :wink:

    You think you found the spring constant, but you made an error. The distance given is the maximum stretch of the spring from its unstretched position. So where's the new equilibrium point? Use that to find the correct value of the spring constant.
