You are going to use F(t)=(momentum) to estimate the force on a skydiver when their parachute opens. Put all of your work on your own paper. Use complete sentences to answer short answer questions. You must show all of your calculations to receive credit.
Go to https:
www.youtube.com/watch?v=io-6uYOQK6A. This is a BBC education video of a skydiver. Watch the video.
1. How can you find the skydiver’s speed from the video?
2. What is the maximum vertical velocity reached by the skydiver?
3. How long did it take them to reach that velocity?
4. How did you figure out your answer to the previous question?
5. Draw a sketch of the skydiver before the parachute opens. Draw and label a
ows representing the forces on the skydiver before the parachute opens. Make the diagram large enough for me to read easily.
6. Assume the skydiver has a mass of 65 kg. Use F(t)=(momentum) to calculate the force of air resistance on the skydiver as they speed up to maximum velocity. Note that “F” is the total force on the skydiver.
7. What is the skydiver’s speed after the parachute has opened completely?
8. How long does it take the parachute to open?
9. Draw a sketch of the skydiver after the parachute starts to open. Draw and label a
ows representing the forces on the skydiver after the parachute opens. Make the diagram large enough for me to read easily.
10. Use F(t)=(momentum) to calculate the force the parachute applies to the skydiver as it opens. Note that “F” is the total force on the skydiver.
11. Explain why the forces you calculated may not be accurate. You can talk to your classmates about this, but you have to write the description in your own words.
