Homework Help: What is the maximum velocity?

  1. Jan 12, 2010 #1
    1. The problem statement, all variables and given/known data
    SHM graph with displacement/time as the axes. Initial displacement is 0.05m and the time period is 1.2seconds. What is the maximum velocity?

    2. Relevant equations
    Just want this section please so I can complete the question by myself.

    3. The attempt at a solution

    N/A

    f = 1/T ??? What would that produce? Let the units help you define the equation. You are trying to calculate a velocity, that requires the equation to produce units in m/s.

    Thanks

    Yeah that was a bit of a brain-fart, since then I have altered the initial post. I know I need displacement and time to give me a speed but surely its not as simple as d/t to give me 'maximum' speed.

    thanks

    How does the displacement of the object vary with time?
    All you have to do then, is to differentiate the expression to obtain a similar one for the object's velocity.

    Boden1563,

    Do you know how to calculate the frequency from the given value of the period?

    Thanks
    Matt
