Yes. Acceleration can be positive or negative. When he jumps out of the airplane and is in free fall, he is accelerating in a downward direction, so his acceleration is negative. When he opens his parachute, he accelerates in an upward direction, so his acceleration is positive.

Would a parachute be balanced when it falls?
As long as it is not accelerating (going faster and faster, or slower and slower), the forces on the parachute are balanced. Initially, the parachute will accelerate - in this case the forces are unbalanced. It will continue accelerating, until the force of gravitation is balanced by the force of resistance.
How does weight affect a parachute?
weight would affect a parachute if you put a 500lb man on a parachute and dropped him gravity would make him travel faster towards the ground compared to if you placed a 92lb boy on a parachute as the parachute applies the same force to both of them but the man weighs more so takes more to slow down and therefor lands down on the ground first By Alister Kelly
What is the name of the force which slows down a man falling with a parachute?
air resistance , maybe!
Does air resistance help a parachute slow down?
Of course it does. If there was no air resistance then the parachute would accelerate at the speed of gravity which is 9.8m/s/s. If a human were using a parachute and there was no air resistance then they would die. "Air resists the motion of objects traveling through it because its molecules collide with the molecules of the object. This resistance to the motion is beneficial because the force acts to slow down a parachute jumper's speed of fall. The jumper falls with increasing speed until the parachute is opened. The greater air resistance acting on the surface of the parachute will bring the jumper to a terminal velocity and will enable the parachutist to safely reach the ground".http://amyallen.org/mhs/applied_physics/physics_of_flight/rocket/parachutes_payloads.pdf
What causes a parachute jumper to slow down?
A parachute is slowed down by air resistance.
Will a man in a parachute when the air resistance is less than his weight accelerate?
Yes, until he reaches terminal velocity.
Who would fall faster a man with a small parachute or a man with a large parachute?
The man with a small parachute will fall faster.
What happens to a skydiver before they open their parachute?
They jump out of the plane and accelerate to terminal velocity.
Can you give me a sentence with the word parachute?
The man jumped out of a plane using a parachute . *-*

When you pull a cord on parachute do you go back up?
You do go up, relative to the cameraman, but you never actually gain altitude. When the parachute opens you accelerate upwards and you fell exactly the same as if you were accelerated upwards from rest.
When Simon goes to the mountain what does he discover?
the man in the parachute
Words used to describe the parachute man?
Ugh!
Who invented the first parachute?
a man named somebody
Can you put the word parachute in a sentence?
The man jumped out of a plane using a parachute so he would fall safely to the ground. We used a parachute so we could land safely on ground.
What is the name of the force acting on a man who is descending with a parachute?
"Gravity" is.
