If a skydiver reaches terminal speed after ten seconds will the skydiver gain more speed during the first second or the ninth second?
I would imagine that it is uniform acceleration up until terminal speed. However, wind resistance will be higher 10000 feet up, so acceleration may be less at the start
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
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.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.
How fast does a skydiver fall?
Speed during free fall can change depending on a skydiver's size and body orientation. In the belly to earth orientation, the speed is about 120 mph. If the skydiver is wearing a wing suit, their vertical speed could be as low as 60 to 70 mph. In a head down orientation, the speed can often be greater than 200 mph.
How can a skier achieve greater velocity than a skydiver?
If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.
Is the skydiver increasing or decreasing his speed during the first 3 seconds?
Increasing.
A skydiver slows down from 65 m s to 5 m s by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
The general formula for acceleration is [(final velocity) - (initial velocity)]/(time required for the change). In this instance, (5 - 65)/0.75 = -80 meters per second per second.
What is the skydiver acceleration?
Upon leaving the aircraft, a skydiver rapidly reaches something called terminal velocity. This is where the resistance of the air matches the mass of the skydiver. At this speed, the skydiver maintains a relatively constant speed. Typically this is around 120mph in a flat body position and takes approximately 10 seconds to reach.

TheI momentum of a skydiver increases as speed increases does the momentum of the earth simultaneously change how much and in what direction how does the system made up of the earth and the skydiver?
For a simple answer, we have to ignore air resistance. As the skydiver's downward momentum increases, the earth's upward momentum increases by an identical amount. The total momentum of the earth-skydiver system remains constant.
Why does a skydiver loose speed when he opens his parachute?
Because it fills with wind and increases his air resistance.
