    The Position of a particle moving along a straight line is given by s=t^2-5t+3

    (I) Draw a diagram to show the path of the particle over the first 6 seconds of its motion
    (II) how far does the particle travel in the first 6 seconds..

    So I have done the first question by simply plugging values of t into the equation but I cannot, for the life of me, remember how to find how far the particle travels
    if the graph is a curve :/

    the particle starts at s =3 and is moving left until t=2.5
    it the reverses direction and moves to the right forever

    Thank you!

    When you said it was a 'bit hard', would you expect a question like this to pop up in the OCR paper M1 paper?
