if there is no air then both will take same time.But due to presence of air person who is without parachute will take less time.
The parachute increase the surface area and so therefore increase air resistance, slowing the person down, and reducing terminal velocity.
yes it is possible to parachute without a "parachute" there is a suit which u wear called a squirrel suite i believe which allows the air to be caught acting as a "brake" there for slowing you down but i am not sure if it works completley
on his but
A parachute slows down the descent of a person by creating drag and increasing air resistance. When a person jumps with a parachute, the parachute opens up and generates enough drag to slow down the fall, allowing the person to land safely without getting hurt.
No. In many movies it appears that someone opening a parachute flies up in the air. However, this is because of the perspective of the camera, which continues falling while the person slows down. Gravity continues to pull the person down to the ground, the parachute only slows them down.
17 mph
A person would sit on a chair without falling threw by having a seat on it and if there isn't too much weight on it.
About 50 degrees
The answer to that is 40-56 mph i quess
Falling from any height can be fatal, it all depends on how you land. A person can trip while walking and land just right to cause a fatality while another person can fall 40 feet and still live. So there is not any real height to consider because its not the factor in falling fatalities.
The parachute will increase air resistance, compared to the person alone.
When a skydiver opens the parachute, he or she does not move upward, but rather, continues to move downward, but at a slower speed. Sometimes there is an illusion that the skydiver is moving upward, because if there are several people skydiving together, and one of them opens a parachute while the others don't, you will see the skydiver with the open parachute moving upward with relation to the other skydivers. But they are all still moving downward, they are just doing so at different speeds.
