=Follow the directions on the Vertical Motion page, to complete each of the sections below. = **__The Word Problem__:** How would you solve for time in the problem your group was assigned? Prepare the equation to solve for time, defining the variables and supporting your choice in equation

This is the correct equation because it's solving the problem for an object thrown.

1) You are competing in the field target event at a hot-air balloon festival. From a hot-air balloon directly over a target, you throw a marker with an initial downward velocity of -30 feet per second. from a height of 200 feet. How many seconds will it take the marker to reach the target?

**__The Parabola:__** Use what you know about parabolas to predict the shape of the graph. What will it look like, and how do you know?

A= -16 B= - 30 C= 200 The magnitude of A affects the width of the parabola. The ( - / + ) determines if the parabola opens up or down. The graph would open down because it's a negative.




 * __The Math__:** Pretend you are the teacher, and this section is your lesson. Post the calculations required to graph the equation and find the solution, and show all the steps to doing so. Teach your audience all the important parts of the graph and explain what they mean for the problem you were given.




 * __The Solution and The Meaning__:** What do the different parts of the graph mean? What does the solution mean?

The solution shows where the object is first thrown and where it landed. The Vertex represents the highest point of the parabola. The y-intercepts shows the height of the problem. The roots explains where the object could land at. The object is in the air for about 3 seconds and i know that because it's the roots, and roots are the solution which your solving for time. 


 * __Reflection__:** How did it feel to do the work and pretend to be the teacher? Do you think you understand the material more, now? Why or why not?

I found doing the Quadratic formula hard. I would stay in task more because, we found out that we had only a little bit of time left and a lot to do in the last minute. This project helped me understand how to do the vertical motion better because i didn't know that 'A' is suppose to be a negative when being thrown. I don't think pretending to be the teacher really gave me any effect. - Jennifer.

I think the part that was difficult was when we had to squar´root because i cant deal with large numbers. What i would do is get help from a teacher or tutor to help me out. this helped me much better in doing the quadratic formula because i thought it was confusing at first but then i found out. it felt weird pretending to be a teacher because it is kind of hard. -Evelyn C. <3
