The weight of the sky diver has minimal effect on freefall time. Body position and amount of surface area exposed for wind resistance to affect are the two largest factors, and are interrelated to one another.
the mass of the skydiver indeed does effect the landing time :D
yes it does affect....more the area of the paper, more is its weight.... more the weight,it falls faster on the grnd due to acc. due to gravity....
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.

The surface area, mass and the shape of the parachute affect the time of fall of the parachutes. Also the height, where the parachute have been dropped from. ( There are more factors that this).
All masses fall toward the center of a larger body at a constant rate of acelleration. On Earth that is 32 feet per second squared. A feather and an anvil dropped at the same time in a vacuum arrive at the ground at the same time.
66.7 m/s2
That depends on the mass of the lead weight and the time it took to cover the rest of the fall.
In the absence of air resistance, it doesn't.
If a weight were to fall on your finger it would almost certainly break or sprain it and you would not be able to use it for some time

If you divide the distance by the time, you get the average speed during that time. The weight doesn't affect the calculation.
In a vacuum, they will fall together. Air resistance might have a minor affect on the results.
