    Can someone kind explain this graph
    And help me with these questions
    estimate the total overall horizontal and vertical displacement of the ball prior to release?
    Calculate the angle of release
    Calculate velocity of release if frame rate was 25hz


    THANK YOU SOOOO MUCH!!!!

    First you need to post the diagram the right way up.

    Like this



    Secondly, the axes names written in are not correct.
    This is not a displacement - time graph.
    The "frame rate" gives you time as I'm guessing each point is plotted an an interval of 1/25 second. (25Hz frequency)
    The axes look like they are the vertical and horizontal displacement of the ball.
    It's the sort of thing you get with a strobe where you see images superimposed every 1/25 second

    Thank you!
    Do you know how i would calculate the angle of release using trigonometry? Where would i get my data from? Thanks

    The tangent of the angle of release (to the horizontal) is measured from the tangent of the straight line drawn from the point of release forwards. Both axes units will be in metres. If both axes had the same scale the angle could be directly measured from the line itself on the paper.
