Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons

Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)
>
Terminal velocity (when forces balance) 687.4 = v 2 * 0.16
Terminal velocity = square root (687.4 / 0.16)
= 65.546 metres per second ( 147 mph) terminal velocity

What are the forces acting on a skydiver?
Drag, I think? drag is good
Are the forces balanced or unbalanced when a skydiver is accelerating downward?
An acceleration requires an unbalanced force.
A 950-N skydiver jumps from an altitude of 3000 m. What is the total work performed on the skydiver?
Work is the force times distance, so the answer is 2,850,000 joules.
What happens to a moving object with zero nets force acting on it?
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
How does forces affect the sport of sky diving?
Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.

When was Eli Thompson - skydiver - born?
Eli Thompson - skydiver - was born in 1973.
When did Eli Thompson - skydiver - die?
Eli Thompson - skydiver - died in 2009.
What is the magnitude of the force of gravity on the skydiver with 845 N?
If you're telling us that the skydiver weighs 845 newtons, then that's the magnitudeof the forces of gravity between him and the Earth whenever he's near the Earth.
When does a skydiver have the greatest kinetic energy?
A skydiver have the greatest kinetic energy as he/she wants to hit the water.
Why is a skydiver not in freefall?
A skydiver is not in freefall when they have opened their parachute. The move from free-fall to controlled decent under a wing.
