Strings help needed

  1. Oct 28, 2004 #1
    Help needed urgently!!!


    A string vibrates according to the equation:

    y=0.6sin px/4 cos 45pt p = pi , x and y = cm , t=s

    (i) what are the amplitude and velocity of the component wave given rise to this vibration?

    (ii) what is the distance between nodes?

    (iii) what is the velocity of a particle of the string at the position x= 2cm and y=3s?

    Any help or ideas would be greatly appreciated!!!!!
