Homework Help: Wave pulse - find amplitude

  1. Nov 13, 2004 #1
    Hey dearest people

    Who can help me solve the following problem?

    A wave pulse is described by,
    y = 0.04exp(-0.6(68x - 7600t)2) [m].
    Here t is measured in seconds, x and y are measured in meters.
    a) What is the velocity of this wave pulse? Be careful to get the sign of the
    velocity correct.
    b) What is maximum amplitude of the pulse?
    c) What is the maximum transverse velocity, dy/dt?

    Many many thanx!!!

    Can you show some effort to try to solve the problem yourself. Here is a hint:

    v = dy/dt
