How much air resistance acts on a 500 N skydiver that falls at her terminal velocity?

500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.

Why is air resistance a frictional force?
If you drop an elephant and an equal weight amount of feathers, the elephant will hit the ground first. The elephant falls faster than the feather because it never reaches a terminal velocity; it continues to accelerate as it falls accumulating more and more air resistance.
What is the relationship between air resistance and the acceleration of falling objects?
As an object falls towards the earth, it accelerates due to the force of gravity acting on it's mass. As velocity increases, air resistance increases. This is in the opposite direction to the force of gravity on the object. Therefore the resultant force on the object is decreased, and the rate of acceleration is reduced. Eventually, the force due to the air resistance is equal in magnitude to the weight and the object has no resultant force acting. At this point the object will be travelling at a constant velocity, commonly referred to as Terminal Velocity.
Is there a maximum speed an object can achieve if dropped from a great height and if so what is it?
Yes, that is known as the terminal velocity. At that speed, the air resistance (pulling up) would be in equilibrium with the gravitation (pulling down), so there is no further acceleration. The terminal velocity depends on the object's size and shape. In general, heavier objects will fall faster.Yes, that is known as the terminal velocity.

Can an object free fall from the stratoshere and achieve a speed greater than Mach 1?
Yes one can reach greater than mach one in free fall from the stratosphere. Acceleration of gravity is about 32 ft. /sec^^2 and barring atmospheric resistance one would reach mach 1 about 34.375 seconds after release after having traveled about 19000 ft. A frenchman named Michel Fournier plans to attempt a mach 1+ jump in late may 2008. He will jump from a weather balloon at about 131,000 ft. and he intends to reach a maximum speed of 1,113 mph before increasing air resistance halts his acceleration and begins slowing him down. The plan is to pass through mach 1 about 37 seconds after jumping. His free fall plan is about 6.5 minutes with a total jump time of 8.5 minutes. If successful he will be the first skydiver to exceed mach 1 and also break the free fall skydiving time record. http://www.legrandsaut.org/index.php?lang=eng These calculations are for a human in free fall, which has a terminal velocity of only about 120 mph in freefall near sea level. This much greater speed is possible because of much less air resistance at high altitude. The impact air pressure felt by him as he falls will be the same as a normal skydiver in free fall from a much lower altitude would feel. A streamlined object dropped from 131,000 ft. could exceed the expected speed of the skydiver considerably because of much less air resistance allowing a greater time for acceleration and a higher terminal velocity.

How does air resistance affect the velocity of an object?
Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.Acceleration is a change in velocity.

Is it true that the steady speed reached by a skydiver is called the terminal velocity?
Yes. Not just a skydiver; anything that falls long enough will eventually reach "terminal velocity", which means that it will continue falling at a constant speed, because the force of gravity and the force of air resistance are in balance.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
the crate will reach terminal velocity last, but hit the ground frist.

increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
Babies have been heard to survive from falls from great heights what is the terminal velocity of a baby at sea level?
I don't know about a child, but terminal velocity for a skydiver is roughly 120 miles per hour, depending on their position in which they fall.
When an object falls through the air and encounters air resistance its overall speed will be?
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
How is terminal velocity reached by a falling object?
While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

When a object falls what does it reach because of air resistance?
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.
A body falls freelywhat is constant?
Gravitational pull is constant...but is limited in a atmosphere due to wind resistance (terminal velocity).
What is the speed at which the acceleration of a falling objects falls to zero because air resistance balances its weight?
This is known as terminal velocity.
How does the weight of a falling body compare with the air resistance it encounters before it reaches terminal velocity?
The weight exceeds the force of air resistance, but as the speed increases the air resistance increases, so the net force (weight - air resistance) falls. When the difference becomes zero the acceleration ceases and you have terminal velocity.
What is velocity at which a falling object travels when the force of air resistance matches exactly the downward force of gravity?
newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity
Why does a heavy sky diver have a terminal speed greater than a light sky diver?
Terminal velocity is when air drag stops you from going any faster when falling. A heavier person will fall with greater force than the light sky diver falls at. So the heavier skydiver will require more force from air in order to keep him/her at terminal velocity
