Work is the force times distance, so the answer is 2,850,000 joules.

Speed of human skydive free fall?
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.
How are total distance and total time related?
total distance / total time = average speed
If you consider the total distance and total time for a trip are you calculating an instantaneous speed or constant speed average speed or non-uniform speed?
If only total distance and total time are considered, the speed calculated (total distance / total time) is the average speed of the entire trip.
What is a natural example of total internal reflection?
If you look at the surface of the water in an aquarium from the side of the aquarium with your eyes just below the level of the water, it will look like a mirror, and you won't be able to see anything above the surface. That's also true of a glass of water, but you can see the effect much more clearly with a container as large as an aquarium. Just make sure nobody jumps around or bumps into the aquarium or the table it is on because those vibrations will result in small waves in the water's surface and it won't look as good.

TheI momentum of a skydiver increases as speed increases does the momentum of the earth simultaneously change how much and in what direction how does the system made up of the earth and the skydiver?
For a simple answer, we have to ignore air resistance. As the skydiver's downward momentum increases, the earth's upward momentum increases by an identical amount. The total momentum of the earth-skydiver system remains constant.
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.

16 Fences in the Grand National. Although some are jumped twice, making a race of 30 jumps in total.
A skydiver started his jump from the airplane. He fell 4.9 m in the 1st second, 14.7 min the 2nd second, 24,5 m in the 3rd second. How far did he fall between the 7th and the10th seconds?
The skydiver fell a total of 94.4 meters between the 7th and 10th seconds. This was calculated by adding the distance he fell in each second (4.9 + 14.7 + 24.5 + 34.3 + 44.1 + 53.9 + 63.7 = 94.4 m).
