    Acceleration
In summary, a paraglider experiences two forces, its weight and a lift force exerted by the air. The lift force has a magnitude of 1900 N and acts in the upward direction. If the lift force suddenly decreases to 1000 N, the resultant force on the paraglider would be 900 N downwards. The relationship between resultant force and acceleration is that acceleration is directly proportional to resultant force and inversely proportional to mass. Therefore, to calculate the vertical acceleration of the paraglider, its mass would need to be known.

A paraglider is flying horizontally at a constant speed. Assume that only two forces act on it in the vertical direction, its weight and a vertical lift force exerted on its wings by the air. The lift force has a magnitude of 1900 N. For both questions, take the upward direction to be the +y direction.
(a) What is the magnitude and direction of the force that the paraglider exerts on the earth?

This correct answer is 1900 N upwards. I need help with the next part.

(b) If the lift force should suddenly decrease to 1000 N, what would be the vertical acceleration of the glider?

If lift force decreases to 1000N, what will be the resultant force on the body now? What relationship does resultant force and acceleration have?
 
  • #3
so would that mean the skydiver falls with a force of 900 N downward? How do I get his acceleration from that because i don't know his mass. Help?
 

Related to Paraglider acceleration problem

1. What is the "Paraglider acceleration problem"?

The "Paraglider acceleration problem" refers to the phenomenon of a paraglider experiencing an unexpected and rapid increase in speed, often resulting in loss of control and potential danger to the pilot.

2. What causes the paraglider acceleration problem?

The most common cause of the paraglider acceleration problem is a sudden increase in wind speed or direction, known as a gust. This can also be caused by turbulence, improper weight distribution, or incorrect wing trim.

3. How can the paraglider acceleration problem be prevented?

To prevent the paraglider acceleration problem, pilots must be trained to understand and recognize the signs of a potential gust or turbulence. Proper wing trim and weight distribution are also crucial in preventing this problem.

4. What should a pilot do if they experience the paraglider acceleration problem?

If a pilot experiences the paraglider acceleration problem, they should first try to maintain control and not panic. They should also try to minimize their speed and make gentle corrections to their wing trim. If possible, the pilot should try to land as soon as safely possible.

5. Are there any technological advancements to address the paraglider acceleration problem?

Yes, there have been advancements in paragliding equipment, such as the use of speed systems and wingtip steering, which can help pilots better manage and control their speed during gusts or turbulence. However, proper training and technique are still the most important factors in preventing and managing the paraglider acceleration problem.
