It lacked for NOT calculating the FORCES involved. Here they are: To estimate the impact force of a 5-meter fall from a 90 kg person, we can use the work-energy principle which states that the work done by the impact force is equal to the change in kinetic energy. When a person falls from a height, they gain kinetic energy, which is then absorbed by the impact. The kinetic energy (KE) just before impact is given by: $$ KE = \frac{1}{2} m v^2 $$ Where: - \( m \) is the mass (90 kg in this case), - \( v \) is the velocity at impact. The velocity at impact can be found using the equation for velocity of an object in free fall: $$ v = \sqrt{2gh} $$ Where: - \( g \) is the acceleration due to gravity (approximately \( 9.81 \, m/s^2 \)), - \( h \) is the height of the fall (5 meters). Substituting the values, we get: $$ v = \sqrt{2 \times 9.81 \, m/s^2 \times 5 \, m} $$ $$ v = \sqrt{98.1 \, m^2/s^2} $$ $$ v \approx 9.9 \, m/s $$ Now we can calculate the kinetic energy: $$ KE = \frac{1}{2} \times 90 \, kg \times (9.9 \, m/s)^2 $$ $$ KE = \frac{1}{2} \times 90 \, kg \times 98.01 \, m^2/s^2 $$ $$ KE = 4410.45 \, J $$ The impact force (F) can then be estimated if we know the distance over which the impact force acts (d), which is the distance over which the person's momentum is brought to zero. This distance will depend on many factors, including how the person lands and the nature of the surface they land on. Assuming a certain stopping distance, we can use the formula: $$ F = \frac{KE}{d} $$ For example, if the person comes to a stop over a distance of 0.5 meters, the impact force would be: $$ F = \frac{4410.45 \, J}{0.5 \, m} $$ $$ F = 8820.9 \, N $$ So the impact force would be approximately **8820.9 Newtons** or ***8.8 KN***. Please note that this is a simplified calculation and the actual impact force can vary. For accurate results, especially for safety considerations or engineering applications, a detailed analysis considering all relevant factors would be necessary.

What is the mask for m8 you blubber and it is hard to hear you😂

I used to work for outward bound doing rock camps in vedawoo. I love that place.

big deal

def not rated R, you can put a crashpad on a cam where you are scared of hitting your head. xD

по шкуродёру почти не переводится

Love it

Where is the second video?

"Potential to fall head first onto a flake even on toprope." Still no helmet. Can somebody explain?

"ON THE GROUND" ? I keep grit out of my rope. Cleaning it as needed at a outside faucet using a device made to wash all marine use rope. I use rope for vertical speleology. Not much U/V exposure in my rope use recreation, eh ?

Mt name is Trent Timmons with 3G Tactics, we are the only online 3gun retailer West of the Mississippi River. Our target market consists of 3gun competitors. Apperal is going to make up 30% of sales. We are excited and would like to know the process in becoming a vendor by providing quality 3gun Apperal, thank you Trent.

Randomly stumbled on this video and as a new climber, this was very informational.

Thanks but my lifetime preference regarding rope information is the Vertical Section of my National Speleological Society. Also the NSS News publication of yearly accident reports and evaluations. Because where we go other people won't..

Sounds very informative but filmed from far too far away to be able to see what you are doing

Got any crotch guards, mask jerk?

Hi, Couldn't you take the mask off for the recording? It seems to be an interesting and useful video, but it is very hard to understand speech with a cloth over your mouth. Sorry...

Online it says that this stove has a baffle, but there is no baffle in this video.

Way to go Shingo!

I had trouble with Instructions on these Crampons last night. I’m a visual learner. Great! Now I can get ready to go climb Mount Everest. Thanks👍🏽

Vedauwoo is life. Catch me out there every weekend

Incredible route! Awesome, aesthetic line

Very good tool to trekking at altitude of 3500m 6500m Karakoram range but sane here.

Bolting cracks is with no excuse a STUPIDITY

wow.. what an amazing climb. have a great day!

I will probably never use one but for some reason, I watched the video :)

Very good this one

Great video! More help on this topic for your exams here. Good luck ua-cam.com/video/Tkmftq1D--I/v-deo.html

Balashahe. Kalmbe

Katya.. Milan

The song is unbearable, otherwise interesting climb

Loose fitting, no seal, and the cotton won't filter out very much at all... so completely ineffective. What's holding it all together besides tension?

Lose the music

The music sucks complete! 🤢🤮

What about lubricate it with some Vaseline or silicon for dry plastics to keep it healthy and enlarge it's duty life ?

Too thick

Nice fold but hard to breath.

Bandana and 2 hair tights! Excellent

Sir please tell me type of ropes

If you own mask or are thinking of making or buying a mask, you must watch: “Five Things You Need To Know Before You Make or Buy a Mask” ua-cam.com/video/xdbZY0sjBtY/v-deo.html and “Find Out If You Have The Right Mask In Two Minutes” ua-cam.com/video/kc0DzYNjCJM/v-deo.html . If you are not sure why you should wear a mask, make sure you watch “Why You Should Wear A Mask” ua-cam.com/video/ydNo1JwS6eU/v-deo.html

Always falls off my ears, dont know what Im doing wrong?

Simple, precise, no bullshit! Well done

nice

_Top rope climbing has never been so comfortable!👉>__lovy.biz/fxa?ロ __ <👈 When I fall... it feels like I am on a cloud. Would recommend to anyone. VERY COMFORTABLE!_

*I have some in 8' increments for my Warbonnet Superfly>>>**allmy.tips/NiteIzeCord?jj╦** and it works great! Now I need more for my Seek Outside 6-man Tipi*

*This stuff is amazing≖≖>**allmy.tips/NiteIzeCord?ssσ** I replaced my tent ropes with this. Now at night when I'm camping and have to 'get up in the night', I can find my tent. They don't say in the description, but the cord reflects red light too. So, if you're using a red light at night to keep from blinding yourself this will work too. Great stuff, a must if you do night time activities.*

Worries about hitting her head. But doesn't wear a helmet. SMASH MY HEAD

It must be the ultimate horror to lead a rout upside down. Holy crap.

똥꿈이 간질간질 하겠다. 똥꿈에 해삼박는 기분이겠네.

i think that she has a infinite cam sistem.o o some thing like that!

Weirdest way I've ever heard someone pronounce "carabiner" lol @2:15
