Man Jumps 23m - What Happened?

  • Thread starter svtec
  • Start date
In summary, a man jumps into a river from a bridge that is 23.0m high. The jump lasts for 2.17 seconds and the diver is traveling at 21.2 m/s upon impact with the water. If the speed of sound in air is 340 m/s, a spectator on the bridge would hear the splash 2.24 seconds after the diver took off. The jump is a difficult physics problem and the answers are worth a significant portion of the homework grade.

Question: A man is jumping into a river that is 23.0m below a bridge.

1. how long does the jump last?
answer: 2.17 seconds
2. how fast was the diver traveling upon impact with the water?
answer: 21.2 m/s
3. If the speed of sound in air is 340 m/s, how long after the diver took off did a spectator on the bridge hear the splash?
answer: 2.24 seconds

TIA...

Yes, those answers are correct. Is that what you wanted?

thanks... i was just checking because i suck at physics.[b(]

i don't have any answers in the back of the book and our homework is worth almost a quarter of our grade.

physics for scientists and engineers = hard.

1. What is the significance of the 23m distance in this man's jump?

The 23m distance is significant because it is an unusually long and impressive distance for a human to jump. It is approximately the length of two standard school buses placed end to end.

2. How did the man manage to jump such a long distance?

The man likely used a combination of physical strength, proper technique, and potentially specialized equipment to achieve such a long jump. Factors such as wind speed and angle of the jump may have also played a role.

3. What kind of training would be necessary to jump 23m?

To jump this distance, an individual would need to have a high level of physical fitness and strength, particularly in their leg muscles. They would also need to practice specific jumping techniques and likely undergo specialized training for the specific event.

4. Are there any potential risks or dangers associated with attempting such a long jump?

Yes, attempting a jump of this distance can be dangerous and carries a risk of injury if not done properly. It is important for individuals to have proper training and supervision when attempting such a feat.

5. Has anyone else ever jumped this far before?

While jumps of this distance are rare, there have been other instances of individuals jumping similar or even longer distances. However, it is likely that this particular jump is a new record for the individual or event.
