You can find this by starting the person, from rest, at an infinite distance from the earth, where the force of gravity is essentially zero, but just enough to start the person falling. By using the correct equations for gravitational potential energy and kinetic energy the total energy at that location is zero. As the person falls he gains kinetic energy and losses potential energy so the total remains zero (conservation of energy) and you can show when he hits the earth his maximum velocity will be 11,000 meter/s (that's approximately 24,000 miles per hr.). His actual velocity will be less because of air resisatance. This is the same velocity that a projectile (like a bullet) must , At Least, have to escape the earth's gravity, when fired out into space.
The speed of an object in free fall increases by 9.8 m/s every second. Therefore, after 2 seconds of free fall, the speed of the ball will be 9.8 m/s * 2 seconds = 19.6 m/s.
The speed of the rock after 5 seconds of free fall would not be 100. The speed of an object in free fall increases by 9.8 m/s every second. After 5 seconds, the speed of the rock would be 49 m/s (approximately), assuming no air resistance.
No, the speed of free fall is not affected by the density of the object. All objects fall at the same rate in a vacuum, regardless of their density, due to the effect of gravity on all objects. This phenomenon is known as the equivalence principle.
The fastest free fall speed slide is called a "drop slide" or "vertical slide." Riders experience a vertical drop at a high speed, creating a thrilling sensation of free falling. These slides are designed to provide an intense and exhilarating experience for adrenaline seekers.
To find free-fall acceleration using only distance and initial speed, you can use the kinematic equation: distance = (1/2) * acceleration * time^2. Since the initial speed affects the time of fall, you would need to know the time of fall or other variables in order to solve for acceleration with just distance and initial speed.

I think that the fastest free fall speed is limited by physics to 32 ft per second per second.

Exiting the airplane without a parachute and having your buddy hand one to you in free fall is fairly daring. It's been done many times starting in the 1960s.
Disneys Blizzard Beach water park, located in Florida, features one of the worlds tallest, fastest free-fall speed slides

The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
