Follow the directions on the Vertical Motion page, to complete each of the sections below.
1) A red-tailed hawk dives toward a snake. When the hawk is at a height of 200 feet, the snake sees the hawk, which is diving at 105 feet per second. Estimate to the nearest tenth of a second the time the snake has to escape. 2) We would use this equation because the hawk is diving towards the ground, in other words the hawk is falling down. 3)The T stands for time, and the V stands for velocity and h naught is the hight. 4)
 * __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 

1) A= -16, B= 105, and C= 200 2) A is positive= the parabola shifts up; A is negative= the parabola shifts down; Fraction= the parabola is wide; Whole number= the parabola is narrow. The parabola is the shape of an umbrella. 3) When C is positive, the graph shifts up, and when C is negative the graph shifts down. The C is the y-intercept. 4)
 * __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?

1) The 3.25 is the x-intercept. The x is 2) 3) 4) We used the quadratic formula because we couldn't use the zero product property. It wouldn't work because the diamond problem because the numbers would be to either to high or to incomplete. That you double check the graph by checking the soultions to the quadratic equation and the graph roots are similar to each other.
 * __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.

1) the solution means that it's going to take about 8 seconds for the hawk to reach the snake. 2) it represents the point at which the object is at it's highest or lowest. 3) the y-intercept is where the graph hits the y-axis. 4) the roots are where the graph hits the x-axis. and it can hit once twice or no times. 5) the hawk will be in the air for about 8 seconds, because the qadratic formula when we pluged a,b, and c in we got about 8 seconds.
 * __The Solution and The Meaning__:** What do the different parts of the graph mean? What does the solution mean?

1) Zach: i had trouble with the math because I'm not good at vertical motion problems. Huy: I had Trouble with finding the Y-intercept in the Parabola Gabriel: I had some trouble processing so much info and narrowing it down to insert it into the wiki. 2) Zach:i would make sure I'm here more often then I was. Huy: I need to correct most my Math next time. Gabriel: I would try to not rush through to finish it on time. 3) Gabriel: I think that the experince with the group explained it into details Zach: It didn't help because we did only one example. Huy: It helped by putting into details/smaller details. 4) Zach: it feels hard to do all this work that some teachers have to do in a day, we had 3 weeks. Huy: In this Project, I feel very difficult with the time limits and the math, since i haven't remember most of math in Vertical Motion Unit Gabriel: In this project I felt like if I did anything wrong it would mean I failed.
 * __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?
