Tell me the fourmla for displacement

  1. Oct 27, 2005 #1
    okay i have a question.
    if a squirrel is at 0 on inital velocity and then is at -2 at final velocity.then what is its displacement?
    And i would appreciate it if someone can tell me the fourmla for displacement.:smile:

    you need to give alot more info to be able to do this problem

    disp= x_o+v_0*t+1/2at^2

    Re: displacement

    I think you would have a negative displacement you instead of going forwards went backwards your displacement would be 2. I think I have problems with physics so.....

    Re: displacement

    Like mathmike said, you need to give a lot more information so an accurate displacement can be given, unless you are searching for displacement as a function of acceleration/time etc.


    [tex]s=ut+\frac{1}{2}at^{2}[/tex] (1)


    Hence, [tex]s=\frac{v^{2}-u^{2}}{2a}[/tex] (2)

    u=initial velocity

    Using the information you have given, formula (1) can be simplified to:


    and formula (2) can be simplified to:


    It is obvious you will at least need acceleration to find the displacement, and yes, the displacement will be negative since your final velocity (v) is negative.
