    1. The problem statement, all variables and given/known data

    The distance covered by an object is given by the equation.
    s^2=at^2+2bt+c
    Then acc varies as?

    I am a beginner please some one explain in the simplest language possible.

    Re: Acceleration

    What is the relationship between speed and acceleration?
    Hint - look at your equations.

    a=v/t
    v=s/t

    therefore: a=(s/t)/t = s/t^2

    specifically - acceleration is the second time-derivative of displacement.
    what sort of answer is expected depends on where you are at in your studies.
