    this is the table sorry if its so un organized

    I need to know the instant velocity at t=0,1,2,3,4 and 5 seconds
    thanks for the help
    and show me exactly what formulas u used show your worlk plzz

    Assuming constant acceleratrion (which does indeed seem to be the case here), the formula for an object's position starting with zero initial velocity is:

    d = 1/2 a t^2.

    Given the values for t and d in your chart you can determine the value for a (acceleration). Then to determine the velocity at any point in time use the formula

    v = at.

    Hope this helps.
