Homework Help: Vertical oscillation

  1. May 7, 2009 #1
    1. The problem statement, all variables and given/known data

    A wire is 2m in length with a mass of 56g. One end is attached to a support, and the other end is attached to a hanging mass of 5kg. The support oscillates vertically with a frequency of 150Hz and 3cm amplitude.
    a) What is the speed of a wave as it travels along the string?
    b) What is the wavelength of the traveling wave?
    c) What is the maximum transverse displacement of the string?
    d) What is the maximum transverse speed of the string? Where does it occur?
    e) What is the maximum transverse acceleration of the string? Where does it occur?

    2. Relevant equations

    The only equations I'm sure about are:
    a) v= wavelenth/T= (f)(wavelength)
    b) wavelength= v/f

    3. The attempt at a solution

    I have a lot of trouble with wave problems and I missed one of the lectures for my class on waves, and you guys are just so helpful here. I was hoping someone could get me started in the right direction on this problem, and I'd really appreciate the help!
