Factoring a Quadratic Equation
I think factoring a quadratic equation is connected with the path of a projectile because when you are factoring an equation, it will give you the starting point and the ending point of a "launch". You can also figure out the speed and the height of the "launch" if you know the beginning numbers. When the equation is graphed, it is easy to see the path that is being taken. -
Quadratic Formula
The Quadratic Formula is ax2 + bx + c = 0. This formula is normally used for finding the roots of an equation. It is better to use this formula because it is faster and easier to organize the parts of an equation. An example of the Quadratic Formula is 5x2 + 2x + 1 = 0. To solve this problem, first find a, b and c. In this case a = 5, b = 2, c = 1. Then use the Quadratic Formula and plug in the numbers. Your final answer should be x = - 0.2 if you did it correctly. -
Projectile Formulas
The two main formulas that we will be using for calculating horizontal and vertical distances are...... Horizontal: x = (forward velocity) x t
To get the forward velocity you type in Cos in the calculator and multiply by the (angle of launch) AND Vertical: (velocity from video) x Cos (angle of launch) Some examples of these formulas using realworld numbers are on the picture that is also uploaded. -
Angle/Distance for Rocket
Angle: 30 degrees Distance: 269 cm The angle of the rocket affects the distance it goes because the further it is pointed up, the further the rocket will go. The angles play a big role when trying to reach a certain distance and height.
