The bean bag will need to meet eye level and go out at minimum 10 feet. Record the time t in seconds that your object is in the air as well as the distance d in feet that it lands away from where it was tossed. (do not include bounce or slide, measure to where it first touches ground). The object will travel in an upside down parabola shape, so will move along a quadratic function path. Round distance to nearest half foot, so either 5 feet, 5.5 feet, 6 feet, 6.5 feet etc.

The equation can be written in the standard form as f(x) = a(x-h)² + k To find the values of (h.k) the vertex, use these equations: The x-coord of vertex is half the distance measured in your experiment: h = d/2 The y-coord of vertex is half the time measured, squared then times 16: k = 16*(t/2)²

If you set the spot where you tossed from as the origin, then the object you tossed hits the ground at point (d,0). So use the values of h, k, and d in the standard form of your quadratic and set equal to zero. Now you can solve for a. See attached example of how to create the quadratic function. Example

State your time, distance, and show your quadratic function.
