The motion of the parachutist after he pulled his rip cord made him appear to be moving upward?
Skydivers do NOT move upwards at all when we open our parachutes. We don't even bounce a little. That is an illusion caused by the camera operator still falling at full speed while the first jumper opens their parachute and slows.
Now, it is possible to move upwards in some limited circumstances. When exiting a fast-moving aircraft while wearing a wingsuit, you can rise above the plane for a (very) short time. Also, once your parachute is open, you can flare your canopy enough to slightly (by a few feet) gain altitude.
It is a common misconception that when a skydiver opens his parachute, he moves upwards instead of continuing to fall. This is merely an optical illusion that makes the skydiver appear to move upward. The person pulling his rip cord to open his parachute appears to move upward because the person taking the video is continuing to fall through the air, while keeping the opening parachute in view of the camera. The changing angle of the shot gives the appearance that the skydiving is moving up.

Why does the author in lord of the flies have the parachutist pulled out to sea?
yup he sure does
What does a parachutists expect he or she chute to do?
A parachutist hopes the chute leaves the pack, and spreads out correctly, when the rip-cord is pulled.
Uniform circular motion deals with objects moving with what speed in a circular path?
When an object is moving in a uniform circular motion while traveling in a circular path, this means it has a constant speed. When an object is moving in a circular path, this indicates it is constantly being pulled towards the center of the circle.
When can a pulley have kinetic energy?
A pulley can have kinetic energy when it is rotating or moving. This kinetic energy arises from the pulley's motion and is the energy associated with its movement.
There is a train which is moving on a straight track without any jerks or vibration. Everyone is asleep and you are awake.Doors and windows are closed. How do you know that the train is moving?
You wouldn't be able to tell. This is because you have no frame of reference to compare the motion to. You judge motion based on a point in space. If all the doors are closed, and all of the windows have shades pulled, the only points that you could compare to are ones that are moving at the same speed as you. Assuming that you feel no vibration, you couldn't tell if the train is stopped or moving. There are ways however to tell motion, just not visually. . If you have a GPS with you, you will realize that the position on the earth is changing.
What is necessary to describe motion?
Something has to either be pushed or pulled by force.
How does the planets orbit?
The planets orbit because of gravity and their momentum. They are constantly flying away from the sun, but at the same time are being pulled toward it by gravity. The end result is that they stay moving in a circular motion around the sun.
Describe what is necessary to cause motion?

Why a cart pulled by a horse can be moved?
The horse is pulling is. Physics. Laws of motion.....
Why is Dick Cheney in a wheelchair at the Inauguration?
Pulled a muscle moving out of the white house.
Are planets pulled into the sun because they are moving?
No they are pulled in to the Sun by the Sun's gravity. Their sideways movement means that this inward pull causes an orbit of the Sun.
On a spinning ride at the fair it is inertia that keeps you moving in a circle?
Inertia is the tendency of an object to resist changes in its motion. On a spinning ride, your body wants to continue moving in a straight line due to inertia, but the circular path of the ride causes you to constantly change direction, leading to the sensation of being pulled outward.
