What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?

At terminal velocity (forces balanced): drag coefficient changes when chute is opened, increasing drag force , net force is upward, deceleration takes place to new (lower) terminal velocity.

The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
What is the acceleration of a car that screeches to a stop if it takes 3 seconds to go from 36 meters per seconds to 0 meters per seconds?
Acceleration = (change in speed) divided by (time for the change) = (0 - 36)/3 = -12 m/s2The acceleration of gravity is 9.8 m/s2, so the passengers are pulled forwardagainst their seat belts with a 'force' of 1.22 Gs during the screech.
Do otoliths detect linear acceleration?
Yes. A gelatinous cover, over tiny hairs in the saccule, which contain otholiths (ear stones) detects acceleration when they are bent during this movement.
What causes pulsation during acceleration - feeling a slight but uniform pulsation in acceleration on the freeway. Also separately moderate vibration from 20-25 and 50-55 MPH?
The vibration at speed is more than likely a tire out of balance or a tire with a broken belt. Have this checked ASAP. The pulsation during acceleration can be many things, from a vacuum leak to a clogged fuel filter. Take it to a tech for service.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
What will be the effect of the acceleration due to gravity while jumping with a parachute?
The acceleration due to gravity doesn't change near the earth's surface, no matter what the cause of your fall is, or what position you assume during the fall, or what you're wearing. But a parachute sets up significant force opposite to gravity, because of air resistance. Since the acceleration is proportional to the net force, it can be reduced when there is considerable force canceling a significant fraction of the gravitational force.
What does Simon discover on the mountain?
Simon discovers that the "beast" the boys are afraid of is actually the dead parachutist. He also realizes the truth about the darkness within each of the boys, symbolizing the presence of evil within humanity.
How is acceleration calcuated?
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
What is any change in velocity during a given length time?
Acceleration is any change in velocity during a length of time.
What is a change in velocity in a certain amount of time called?
Acceleration is any change in velocity during a length of time.
What is the formula you use to dertermine acceleration?
Average acceleration during any period of time = (change in speed during that time) divided by (length of the time period).
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
To determine acceleration you must know the change in velocity during each unit of what?
"time"
What is the equation used to calculate the accerleration of an object?
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
Change in velocity divided by the thime it takes for the change to occur?
That would be the magnitude of the average acceleration during that period of time.
What will happen if a parachutist opens its parachute before reaching its terminal velocity?
During free fall, the parachutist reaches a terminal velocity (a constant velocity) of somewhere between 120 and 180 miles per hour. (If you go feet first, you go faster than if you lie on your back or front). When the parachute opens (hopefully), the terminal speed is reduced to around 12 miles/hour.
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
