Velocity and height at each time interval

  1. Sep 15, 2014 #1
    1. The problem statement, all variables and given/known data

    I want to calculate velocity and height at each time interval
    Time intervals: 1,2,3 (seconds)

    equilibrium height = 3 meters
    amplitude = 0.2
    angular frequency = 48 rad/s
    phase shift = 60


    2. Relevant equations

    y(t) = equiheight + Amplitude*sin(angfre*t + phaseshift)

    3. The attempt at a solution

    I have no idea about where to start. Please help.

    Hello MM, and welcome to PF.
    You could start with the height, for which you have presented a relevant equation. Nothing stops you from filling in equiheight, Amplitude, angfre, t and phaseshift, right ?
    Then, for v you will need another equiation. No idea whatsoever ?

    Exactly. I know what you are saying about plugging everything in. What if we use Euler's algorithm to find the answer ? Any ideas about that ?

    No can do: In the first place it isn't mentioned under 2. Relevant equations. :smile:
    And if it were, why on earth would it belong there ?

    Do you know what to do to determine the velocity when an expression for the position is given ?
    (Hint: consider the definition of velocity)

    Euler's algorithm is for numerical integration.

    [edit] And: if you "know what you are saying about plugging everything in", please show it, just to be sure things go alright...
