Homework Help: Simple problem concerning waves.

  1. May 25, 2012 #1
    1. The problem statement, all variables and given/known data
    My professor has given us a pset with this problem:

    A plane mechanical wave is represented by the equation [itex]y = 30 sin(30\pi t + 0.03 \pi x)[/itex]
    Where [itex]y[/itex] is measured in cm, [itex]x[/itex] is measured in metres and time [itex](t)[/itex] is measured in seconds. Find
    (i)amplitude of particle velocity

    2. Relevant equations

    3. The attempt at a solution
    While I know how to find (ii), I don't know how to find out (i). Can somebody please tell me ?

    What are the particles to which the question is referring? What actually moves when the wave passes a location?
