Factoring a Quadratic Equation
Factoring a quadratic equation can help determine a path of projectile becuase once you factor the problem down you will have to differnt "X" values. Those "X" values will be your two points on the X-axis. Those points are your starting and ending points of when the ball or object hit the ground -
Quadratic Formula
Quadratic Formula= -(b)+and- sqrt((b)sq-4ac)/2a
This equation finds the number where both of the X values hit the X axis at. This is an advantage becuase with certain numbers in an equation you cannot divide then into a whole number so it would be very difficult and almost impossible to do without this formula. For example if you were given the equation 0=3x(sq)+2x-4, your X values would not be a whole number so you need to use the quadratic formula and fill in the numbers (a=3, b=2, and c=-4). -

Projectile Formulas
In order to calculate the vertical distance of the projectile the formula you have to use is Y=-490t^2+(upward velocity)*t+(starting height). You then put it into the quadratic formula. For example if our upward velocity was 144 and our starting height was 46 then our answer ended up being .49sec. To calculate the horizontal distance the equation you have to use is X=(forward velocity)*t. For example our forward velocity was 249.42 and t=.49 so our horizontal distance ended up being 122.22cm. -
