The original equation was h=-16t^2+vt+c. T is the amount of time the object is in the air. C is our starting height and h is our height after t seconds.
What we needed to find was the initial velocity, which is v. We decided to throw a cheerleader in the air/ cheer stunt to do our experiment. We needed to find out how long it took the cheerleader (ft/s) to go up in the air and then come back down and how high she would go.
When we did the experiment, the cheerleader went up approximately 5 feet in about .16 seconds. We then took our data from the experiment and plugged the numbers in for the variables. Our variables were: t=.16 and c=4.8. We also found the vertex, which was our maximum height, and it was (0.16, 5.22)
