Weaks Period 4 Abby,Mauresha,and Shakur Group 9

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. We choose the object dropped equation because the acorn fell and was not thrown or launched.

 6) An acorn falls 45 feet from an oak tree. How long does the mouse on the ground have to move away before getting hit on the head? ,

We choose the object dropped equation because the acorn fell and was not thrown or launched. because once the acorn hits the ground their is no height,mean that the equation is set to zero. because the initial height is 45 in feet from which the object is launched or dropped.This is important because it lets you know what the initial height was from which is was dropped.

is the equation in standard form.


 * __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?



Our prediction is that the effect that a will have on the graph will make it narrower. Its negative so it will open down ward, and its a whole number thus becoming narrow.If a it was a fraction it would be wide. Our prediction of c on the graph is that if c is positive it shifts the graph up and if negative, it shifts the graph down.

Since the formula to solve for the discriminant is the discriminant


 * __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.

roots=  this is the vertex this is the axis of symmetry which is 0

. 1.It will take 1.6 seconds before the acorn hits the ground and that is how much time the mouse has to move before getting hit on the head 2.The initial height because the height of the point from which the acorn fell from so therefore the y-intercept is (0,45) 3.The y-intercept is (0,45) because the graph intercepts the y-axis at 45 4.The roots represent the time the acorn hits the ground because from the time the acorn fall and the the time the acorn hits the ground is the time 5.The object is in the air for 1.6 because is approximately 1.6 which is the initial time
 * __The Solution and The Meaning__:** What do the different parts of the graph mean? What does the solution mean?


 * __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?

Abby's reflection- 1) What was difficult about this project was that how to use math type and the graphing on the laptop. It was difficult because I never used those types of applications before. 2) What I would do differently to run the project smoother is to pay attention, to **ONE** thing. Because I write in another paper and I distract myself at times. What I would also change is in my suggestion is to get more laptops. Because with only one laptop it's complicated to share a single laptop. 3) This project helped me understanding to keep on task. Yea I might be off here and there but I no how to do the job. And I learned to how to use the new types of applications, just in case for the future. 4) I didn't feel like a teacher because Ms.Weeks would still tell me to go back on to the topic. But it also felt goo to understand and to learn something new.

Shakur's reflection- 1) I fell that finding he roots and graphing the parabola was difficult because it was hard to find the right procure to use in our to graph, find, and solve for your answer. 2) I would take more detailed notes from the book and from the teacher in order to get a much deeper understanding. 3) Yes& No. Because I feel that the problem was to vauge but I also feel hat there should have been a simpler topic such as a multi step equations. 4) I felt that the teacher should have went over the material before giving us them project/assignment.

Mauresha's reflection- 1)The whole project was actually a challenging for me presonally because me and vertical motion really isn't my friend unfortunately. Also the part of graphing the parabola was majorly difficult for me. 2) What I would do differently next time is take more time to help more in my group & engage more. 3) I don't really think I benefitted from this project this much because am absolutly lost when it comes to vertical motion & I didn't even try really and that's my fault next time ill participate more next time around. 4) I don't really know how it felt to be a teacher because I didn't participate as much as I should of so I regret that.
