Finding speed from acceleration

  1. Aug 8, 2008 #1
    Hi all
    1. I have given acceleration at two particular points and the time required to reach from first point to second point

    2. Now how can I calculate the speed at those two points.
    3. If suppose I know speed at first point how can I calculate speed at second point

    Thanks in Advance

    Vf = Vi + at
    Vf^2 = Vi^2 + 2as
    s = (Vi+Vf)/2*t
    s = Vit + 1/2*a*t^2

    These are the kinematics equations
    Vi is initial velocity.
    Vf is final velocity.
    s is displacement
    t is time
    a is acceleration.

    Use these equations accordingly, from the information which is given to you.
