Math Book Alan, Carlos, Kevin, Noah Weaks Period 6

Follow the directions on the Vertical Motion page, to complete each of the sections below.

 * __The Word Problem__:** 5) You drop your keys from a window 30 feet above the ground to your friend below. Your friend misses them. How many seconds did it take for the keys to reach the ground?


 * __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?

We think the parabola is not going to be not very wide because the number is high.The (+ and -) sign effect it because it determines whether it goes up or down similar to c. **A=-16 B=0 C=-30**

T=Time, H=hieght on impact, V= velocity, A= -16, B=0, C=-30
 * __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.

This is how we found the time it takes for the keys to reach the ground.



The roots are 1.37,0 and - 1.37,0.


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

1. The meaning of our problem was how long it took for a set of keys to fall 30 feet to the ground without stopping. 2. The vertex is the height it was dropped at because it is where the man or woman dropped the keys which was 30 feet in the air. 3. The y-intercept is similarly like the vertex where it is the height it is dropped at since they are both the same. 4. The roots represent where the keys stop because where it stops shows us how long it took for the keys to get to that particular spot. 5. The object was in the air for approximately 1.4 seconds because when it is going down you have to find the roots which are where they fell or when it stop falling.


 * __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?

**Carlos' Reflection:** The most difficult part of this project was doing the math. This was kind of hard because it was hard to remember all those equations and remembering the steps. I think this project would go smoother if all the people in the group stayed focus. We did have a lot of fun time, but there are times to be serious. This project helped me kind of remember the equation, but i am still kind of lost. I really like these kinds of projects, just on different topics. I learned that i wouldn't want to be a teacher. It was kind of fun, but not as fun as i thought.

**♫Kevin's Reflection♫:** One thing that was arduous to do was finding the equations and solving it. Something i would do disparate to make the project run smoother is to work contemporaneously and solve\finish something one at a time. Doing this project helped me understand quadratic equations and vertical motion a slightly easier. It only helped me a little because it wasn't my responsibility to solve the equations and do the math. It felt the same to do the work and pretend to be the teacher although i didn't pretend to be a teacher really. But i wouldn't want to be a teacher because its something I dislike. **Alan's Reflection:** The most difficult part was solving the problem. it was really hard to remember the equations and remembering the steps. Maybe we could have completed this faster with the laptops. The problem helped me comprehend vertical motions a little better but i still have trouble remembering the steps.It felt really dull to be a teacher.
 * Noah's Reflection:** The most strenuous undertaking was comprehending how to work out the math problems. Next time I should make Alan and Kevin actually assist their confederates. I perceived the material more, albeit i haven't used this "modus operandi" in virtually a month. I felt i could usurp your position with my superincumbent and paramount acumen. But your job is not for me to supersede...
