 * Team members:** **Facilitator**: Erick G. **Recorder:** Oliver F. **Number Cruncher:** Miguel P.

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

 * __The Word Problem__:** 7) A lacrosse player throws a ball upward from her playing stick from an initial height of 7 feet and an initial velocity of 90 feet per second. How long before the ball hits the ground?

2.)This is the appropriate equation for this problem because our question talks about velocity and the time and height.h stand for height.3.)T stands for time.V stands for velocity.H0 stand for the initial height where the object is dropped from. So when you plug in your #'s, you will get velocity and h replaced by the #'s based on the question. This is how you'll find the discriminant which tells you if you will have two roots, one root, and even no roots.
 * __The Parabola:__** a is -16 b is 90, c is 7. The effect of a is that it will make the parabola go downward because there is a negative number that is small which is -16. The magnitude or the shape of the parabola will be skinny because the higher # on a will make it narrow. The effect on c translates the graph up or down.

This is how you find the vertex. This on top will tell us whether the parabola will have 2 solutions, 1 solution, or even no solution by using the quadratic formula. 2. The vertex represents the highest or the lowest point of a parabola which is on the axis of symmetry. Why because it shows the axis of symmetry intersects the parabola at the vertex. 3. The y-coordinate shows the location on the y-axis of a point in the coordinate plane. Why because you need the y-coordinate to get the y-intercept. 4. The positive root represents how much the object will be on the air until it hits the ground. The negative root represents how long the object not being thrown from it's regular height but from the ground level until it gets to the regular height. 5. The ball will be 5.7 seconds in the air because we did the quadratic formula with out vertical motion equation and found the answer to be 5.7 because the other answer was negative.
 * __The Math:__**
 * __The Solution and The Meaning__:** 1.The solution tells us that the ball will take 5.7 seconds in the air until it touches the ground.

Miguel's ** **Reflection:** There were some parts that were hard the hardest one of all the section's was the 4th one which is the Math. I think me and my group had a lot of conflict because the vertical motion problem was harder to find a solution that a quadratic equation. What I would do differently is to try to not finish at the last minute because honestly we finished almost all the sections at the last minute. This project did help me on the vertical motion problems because now I can see how it would look like in the graph form. It felt kind of stressful because I had some problems on finding some answers.
 * __Reflection__:
 * Oliver's Reflection:** One thing that was difficult for me was finding the roots and how to draw a parabola because we had to use lots of ways to find these like the quadratic formula. The thing I would do differently is not finish at the last minute because we will have to rush and we will probably do every thing wrong with out checking what we did. The project I did helped me on solving any vertical motion problem just by doing the same procedure and how to draw the graph with the roots. It will help me on any future problems I will have during my school carrer.

Erick's Reflection : One of the things that was difficult for me was finding the equations because we didn't understand what to do with the with the square. One thing I would do different is not to go to any other groups and just go to my group. another thing that was difficult is save the screen shots and name them differently so we don't have to take the pictures all over again. The project I did helped me on solving any vertical motion problem just by having my team mates share their ledge with me to help me under stand the problem better. It will also help me with many other problem in my school and future carrier
