What do parachutes do that cause skydiver to slow down?
simple air resistance
What happens to the air resistance as the parachute opens?
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
How does a skydiver float?
The momentum of the diver with the gravity against the thinner air in the altitude and the position of your body cause you to slow down your fall.
How does a skydiver us friction to slow down?
A skydiver experiences two forces when in freefall. One is gravity, which he has no control over. The other is air resistance, a type of fluid friction. By changing the position of his dive relative to his direction, a skydiver can fall faster or slower, spin, etc. By spreading his limbs out and assuming a laying position in the air he would produce the most air resistance and slow his descent. At some point, however, the parachute (also causing air resistance) would be deployed and slow him further.
What is the skydiver's downward velocity after 2 seconds?
Assuming we neglect air resistance and start from rest in the vertical plane - use v=u+at so v = 0+(10x2) assuming g = 10N/kg =20m/s In practice it will be less because air resistance will tend to slow the skydiver down.
When a skydiver jumps from a plane he is in a condition known as what?
Panic?Terror?Exhilaration?No, "FREE-FALL". Although one or more of the first three are likely, as well.By the way; a skydiver is only in freefall for about a second after the jump. After that, the air resistance of his body begins to slow him down until he reaches "terminal velocity".
A skydiver slows down from 54 ms to 4 ms by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver?
66.7 m/s2
How does a skydiver change his or her speed?
Just as a leaf falls slower to the ground than a tennis ball, a skydiver changes his/ her body position to change the amount of surface area that is affected by air resistance. A flatter body position, for example, will slow a skydiver's freefall rate from a normal arched position.
A skydiver slows down from 54 ms to 4 ms by opening his parachute. If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
66.7 m/s2
Skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
80 m/s 2 up
What is slow down?
its when something is slowing down
A skydiver slows down from 65ms to 5ms by opening the parchute if this takes 0.75 seconds what is the skydiver's accerlation?
66.7 m/s2
