Comments Page 1 Motion of a Cannon Ball over a Hill In this model a projectile - lets say a canon ball - is fired from the left hand corner of the graph show the Graph worksheet, with the right hand corner of the "land" as its target. You can control the proje by changing the values for its velocity and angle, shown below the graph. Notice how much easier it is to see the effect of changes in the parameter values if those values are same worksheet as the graph. This was a design limitation in the Flight of an Arrow model. You can also control the shape of the hill by changing the values of A, B, and Y in the Hill_Paramete worksheet. Changing the value of A changes the level of the land on the right hand side of the hill. B the height of the hill and Y changes the position of the peak and the width of the hill. (You can't chan value of s since it is calculated from Y.) After you have hit the right hand corner with this hill shape, change the hill shape a little and try aga Change A to 0.6 and B to 2 for example. The graph is plotted using points in the Hill_and_Projectile_Data worksheet.
