10. You can out run a lava flow … METRIC

November 17, 2018

This is a rework of a previous post with full calcs.

Every volcano disaster movie from Volcano (1997) with Tommy Lee Jones to Dante’s Peak (1997) withDantes_peak_ver2Pierce Brosnan someone somewhere tries to out run a lava flow. Is this possible?

The answer is maybe. You will find everything you want to know about lava flows here.Volcano_ver2

On January 10,1977, at Nyiragongo lava sprang from the sides of the volcano moving at speeds up to 40 miles per hour (60 km/hr). About 70 people were killed.

The fastest Lava flows recorded were in Hawaiiin 1950 when Mauna Loa erupted. The lava traveled at 10 kilometers per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 97 kph.

Speed of average sprinter = 16 – 24 kph

 

Can you out run a lava flow?

You would be scorched after 3 minutes!!!!

4. If you are involved in a car chase, hijacking, explosion, volcanic eruption or alien invasion, you will not go into shock.

200px-2012_PosterHere are just a few of the popular disaster movies:200px-Armageddon-poster06 Avalanche (2001), Earthquake (1974), Armageddon (Involves meteors 1998), Deep Impact (More meteors 1998), 2012 (Tsunamis, earthquakes, the lot. 2009), Twister (tornadoes 1996), Backdraft (Fire. 1991) and Towering Inferno (They don’t make thunderous movie titles like that anymore. 1974)  

But what percentage of people involved in, say, an explosion suffer from SHOCK! There are many statistics about Post Traumatic Stress Disorder (PTSD) available. In one excellent study (The National Centre for PTSD Journal

http://www.hawaii.edu/hivandaids/Pubs/National_Center_for_PTSD_Clin/National%20Center%20for%20PTSD%20Research%20Quarterly%20Spring%201992.pdf  )

involving an explosion in a paint factory in Norway (1976), the 246 employees were ranked for their exposure to shock as follows:. 200px-Twistermovieposter

A. 66 Narrow escape

B. 59 Involved but not in danger

C. 121 Not present on the day.

200px-Deep_Impact_poster 80% Group A suffered shock and PTSD. Both Groups A & B showed symptoms of PTSD 7 months later. If, say, a plane crashed into your school and your class survived with minor injuries calculate  how many students in your maths class would go into SHOCK and how many would be left to take action using the above statistics.

NOTE: Many schools in Australia today not only practise fire drills but terrorist attack lockdowns.

8. You can survive any amount of beating in a fight.

Die_Hard_With_A_VenganceLethal_Weapon_4_PosterEvery action hero gets into a fistfight. James Bond, Jason Bourne, Indiana Jones. Then there are all the stars known for their fight scenes. Sylvester Stallone ( Rocky),  Arnold Schwarzenegger (True Lies), Jackie Chan (Any movie), Bruce Willis (Die Hard 1,2, 3 etc), Mel Gibson (Lethal Weapon I, II, III etc), Jean Claude Van Damm (Blood Sport, Street Fighter), Brad Pitt (Fight Club) and so on.

Fight ClubBut can the human body take this punishment?

 

We can work it out. Measurements taken at The University of Manchester have shown that local boxing hero Ricky ‘The Hitman’ Hatton really does live up to his name. (DailyScience)

ricky 'the hitman" hatton

Ricky ‘The Hitman’ Hatton can pack a punch!!!!!

 
punch-1-mathspig

punch-2-mathspig

Similar results were found at Uni Manchester BBC (Force of boxer’s punch measured)


punch-3-Mathspig

So one punch is equal to being hit by a car …… if only for a split second!!!!!!!!!!! Nevertheless you can be killed by this one punch.

You’ll find some great punching physics here

Can you out run lava?

Work it out mathspigs. You are 600m ahead of the lava flow and you need to get up a hill to escape, which is 1000m away. The lava is flowing at 30 kph and you are running at 18 kph.

running man

Will you make it??????
