In a free fall ride, the object (car) is projected, at time 0, with some initial velocity. Suppose that velocity has a horizontal component of h metres per second and a vertical component of v metres per second.
It is assumed that the only force acting on this body is that of gravity. Air resistance is assumed to be insignificant. Consider the position of the car at time t seconds after "launch", measured from the launch position.
There are no forces acting on it in the horizontal direction. So, following Newton's law, it continues to travel in the horizontal direction at h metres per second. And therefore, its position is ht metres from the launch position.
In the vertical direction, the force is a downward acceleration of g metres per second2. So the vertical position at time t, is vt - 1/2*gt2.
Thus x = ht
and y = vt - 1/2*gt2
From the first equation, t = x/h. Substituting this in the second gives
y = v*x/h - 1/2*g(x/h)2 = -(1/2*g/h2)x2 + (v/h)*x
that is, y = Ax2 + Bx for some constants A and B
[specifically A = -(1/2*g/h2), and B = (v/h), but the exact values are not relevant here.]
Now y = Ax2 + Bx is the quadratic function model, therefore it is a suitable model for such motion.

What is a real life example of the sine function?
A real life example of the sine function could be a ferris wheel. People board the ride at the ground (sinusoidal axis) and the highest and lowest heights you reach on the ride would be the amplitudes of the graph.

ride in a plane. you would fly a plane
What is an easy way to go the quadratic formula?
the quadratic formula is really complex. so, if you can avoid it, you should. one way i do this is by getting the trinomial into X^2 - 2YX + Y^2 = 0 form. here's an example lets say we have x^2 - 2x - 5 = 0 normally we would have to do the quadratic formula however, if we get it into this form, we can get x^2 - 2(1)x + 1 = 6 all i did was add 6 to both sides of the equation. you can now simplify the left side of the equation, and be left with (x-1)^(2) = 6 to get ride of the exponent on the left side, find the square root of both sides. this will leave you with (x-1) = (+ or -)radical(6) add one to both sides and you will get x = 1 (+ or -)radical(6) therefore, x can equal 1 + radical(6) or 1 - radical(6) now, this may seem complex, but it is easy once you get used to it. It is far more efficient than the long quadratic formula.

How fast does the flock fly in Maximum Ride?
Well, they all fly at different speeds, but Max can fly over 200 mph and freefall at about 250.
Which is the best type of graph to model the speed of a roller coaster over the full two minutes it takes to complete the ride?
A discrete graph. A discrete graph is a visual function that displays data that generally represents counts of things.
Who is the model on Maximum Ride graphic 3?
that iggy.
How long does it take to skydive from plane to ground?
I went tandem and you freefall for about a minute (which feels like much longer) and you parachute down for a little over 10 minutes. We jumped from 14,000 ft. Depends on the type, static line you only freefall for about 5 seconds before the chute deploys. For deployments above 12,000 ft, freefall lasts between 45-60 seconds with a chute ride for 4-12 minutes. After 50 mph you do not feel the sensation that you are falling. Freefall meets maximum velocity at 120 mph. Capt. Joe W. Kittinger achieved the highest and longest (14 min) parachute jump in history in 1960 as part of a United States Air Force program testing. Freefall lasted 4 minutes and 36 seconds.

What was the accident that occurred on the ride Demon Drop at Cedar Point Ohio in the 80s?
There has never been an accident on Demon Drop. However, there was an accident on the freefall ride "The Edge" at Six Flags Great America in Gurnee, IL, where a supporting cable snapped, and the car plummeted to the bottom of the tower. Four teenagers were hospitalized and later released. After this accident, more safety precautions were instilled in the ride, including double the number of anti-rollbacks. When the ride reopened, ridership was low, so the ride was dismantled in 2006, and the parts are used to maintain Demon Drop at Cedar Point.
