I guess it was a brake failure. Happens every day, usually with trucks and buses. And now with small cars even? A disease? A virus? 😱 (A brain disease🥴)

Far more likely to be accelerator jammed to the floor. Hitting the wall at the speed necessary to demolish it and have the car follow through leads one to think he was going way too fast for a car park in the first place. Maybe got the pedals mixed up..? Or foot jammed, dropped his phone etc.

It takes a special level of driving skill, and concentration to crash through a wall in a garage and dump your car below, unless it was a heart attack or brake failure. 

 

Not really.

Just look at what the wall was made of, based on the photo provided.

 

Looks like some sort of plaster board, having two layers of board.

 

Should have been reinforced concrete. But, apparently NOT.

I'm not surprised the driver had only minor injuries.

 

Using the equation F=ma, we can calculate the force and v1 and v-final, before impact.

 

Approximate speed in MPH is 30 miles per hour.

 

I just hope the driver was wearing a seat belt, which is mandatory.

Look at the barrier wall on the floor above it.  It  ends with a large gap with no barrier wall.  Safety is their priority???

We can only hope that you do not drive at all, since there seem to be serious problems with your eyesight.

I love it when people write scientific stuff that they do not understand. F = ma will only tell you the force the vehicle exerts on the ground, if you know its mass. I think you will need v^2 = u^2 + 2fs. Good luck. I think you will find that it is about 17 m/hr.

Maybe too sober and got cocky......if she'd been drunk she would have paid more attention to what she was doing.

Older drivers in modern cars can get flustered and make a mistake and then panic.

It's good the old fella didn't get badly hurt.

 

This looks like one of the many Lumpini Pinklao buildings, but for some reason it's not made clear in the article. Is there a reason for that? For example, was that wall built strong enough? Asking for a friend.

No problem...because...

At least I am smart enough to derive just about anything from this simple equation....

 

This is what is so nice about Physics, and science in general.

In Japan, elderly drivers must take a vision, written and driving test every two years to retain their driving licenses.   Even so, there are many accidents similar to this one.

Unless the wall continues in a curve around the side that cannot be seen due to perspective.  Look at the remains of the wall he went through, there is a wall to the side.

Amazing that he survived and lucky nobody was walking below. 

Everyone knows that in Thailand you have to look left, right, ahead, above, behind & below, before walking on the road/footpath to have a 50% chance of survival. 🤪

He was doing nearly 50kph?  How do you know that?

 

I know this from Newtonian (classical) Physics.

 

Easy enough to calculate using the laws of Classical Mechanics.

 

If you understand F=ma, then you can calculate velocity and momentum and force exerted on the ground by the car, and likely force of driver's head on windshield (windscreen).

 

This is why Physics is so relevant in our everyday lives.

Often a woman who leaves it in reverse after parking, gets in and forgets, only to accelerate the wrong way, they usually die.

Pedant alert!

 

For an object in free fall, m (mass) has no relevance - Galileo.

But I think your guesstimate of 30mph could be pretty close.

vf = g * t would be the formula, but we can't calculate the time without knowing the height.

Guessing a 15m fall (1.75 seconds) would give 17m/s or 38mph.

I think he was attempting to calculate the 'speed' at which the the vehicle hit the ground.

 

Av height of a floor: 3m  (so 15m) I calculate that the car was travelling at 61.7kmh (38.8mph) when it hit the ground.

Actually, mass does have relevance, unless we are talking about a perfect system, with no air resistance to muck up the calculations.

 

Unfortunately, in Thailand, there is some sort of atmosphere we must take into account.

 

But this is not what I was saying.

 

We CAN use F=ma to derive all the equations required to know how fast the car was travelling when it impacted the ground.

The mass of the car and atmospheric drag have a negligible effect over short distances like this.

 

For much higher falls where terminal velocity might be reached, the impact speed would be limited to the calculated terminal velocity of around 179 m/s.

 

For a 15-metre drop, the original calculation of 17.14 m/s remains approximately correct.

 

Thus: The calculated 'speed' at impact 61.7kmh (38.8mph) is not impacted by mass or atmosphere (the impact of mass / size / atmospheric density is minute to the point of being negligable).

I was not attempting to calculate the speed I stated.

 

I used 30 feet height from the ground, of 3rd floor.

Anyway, it really does not matter that much, unless you love Newton.

 

Far more interesting to calculate the reasons for the shoddy parking garage wall construction.

 

And, also, the surprise on the woman's husband's face when she told him.....Honey...I went flying today.
