After opening the parachute do you go up?
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.
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
Why does a parachuete make a person falling from a greater height fall more slowly?
It increases the drag coefficient (dc).Say freefall terminal velocity (vf) = 60 metres per secondSay landing terminal velocity (vl) = 6 metres per secondMass of freefaller (m) = 70 kgAcceleration due to gravity (g) = 10 (m/s)/s (approx).Force down (newtons)= mass * acceleration due to gravityForce up (newtons) = drag coefficient * velocity squaredTerminal velocity is where forces balance:m * g = dc * v2.Freefall velocity (parachute closed) = 60 metres per secondm * g = dc * (vf)2then:dc = (m * g) / (vf)2dc = 700 / 3600dc = 0.194 (prior to parachute opening).Landing velocity (parachute open) = 6 metres per seconddc = (m * g) / (vl)2dc = 700 / 36dc = 19.44 (with parachute open)

What effect would opening a parachute have on a sky diver's fall?
It slows down their fall so when they reach the ground their legs or any other part of the body will not be broken.
When skydiver slows down from 54 meters to 4 meters by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!

What A skydiver slows down from 54 ms to 4 ms by opening his parachute this change takes 0.75 what is the skydiver acceleration?
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.

66.7 m/s2
A skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydivers acceleration?
80 m/s2 up

What are the odds of a parachute not opening?
The odds of a parachute not opening properly can vary depending on factors such as equipment, training, and environmental conditions. Overall, modern parachutes have redundant safety features to minimize this risk, with failure rates estimated to be very low, around 1 in 1000 jumps. It's important to always follow proper procedures and maintenance protocols to ensure safe operation.

What happens immediately after skydiver opens her parachute?
When her parachute opens, the air resistance increases. Now there is a resultant force going upwards on the parachute. The increase in air resistance occurs because when the parachute is opened there is a much larger surface area (than before) so the particles of air are much more likely to get 'caught up' in the parachute unable to pass easily, therefore creating more air resistance (an upwards force) and so slowing down the parachutist. NOTE: The parachutist does NOT move upwards after the parachute has opened, they just slow down. This effect comes from when a parachutist with a camera is filming opposite, they are still falling rapidly while the other person's parachute has opened, therefore passing them as they continue to freefall, and so the parachutist opposite appears to move upwards after opening the parachute.
What is freefall delay?
In skydiving, freefall delay is the amount of time allowed for the parachuter to freefall, that is, fall without opening their parachute. This is the time from leaving the plane to opening of the parachute.
Do skydivers spend the first several seconds of their jump in freefall?
Yes, skydivers do spend the first several seconds of their jump in free fall. They do not usually open their parachutes until they are about 2,000 feet above the ground. Opening the parachute too soon might cause the parachutist go extremely way off course or result in an updraft that will cause injury.
What is free combat?
The Military Free Fall Parachutist Badge is a military badge of the United States Army and United States Air Force awarded to qualified U.S. Army and U.S. Air Force personnel as high altitude parachute specialists. It also is called HALO (High Altitude Low Opening) Wings.
