How many G's do you experiance on Top Thrill Dragster at Cedar Point?

[Chrishuff1]

Anyone know?

 

[Pastore]

First link on Google

 

[Chrishuff1]

I've been through the site and I can't find anywhere where it says how many G's you experiance.

120 mph in 4 seconds, that's like a 100 G's.

120 mph = (120 miles/hour) * (1 hour/3600 seconds) * (1000 meters/0.62miles) = ~53.76 meters/second

Assuming constant acceleration:

To reach the final velocity the acceleration must be:

a = (53.76 meters/second) * (1/4 seconds) = 13.44 meters/second^2

1g = 9.8 meters/second^2

(13.44 meters/second^2) * (1g/(9.8 meters/second^2)) = 1.37g's

That can't be right...

(If it is, then it's weak!)

 

[Chrishuff1]

I went on Face Off at Kings Island and that only goes like 62 and we experiance 3 or 4 G's so I'd think 120mph would have around the same or a little more possibly?

No way. It has to be much more than that.

well, i am going hopefully soon. but from what i have heard its amazing just cuz they light up the tree, it hits green, and you dont go, you relax, and you go.

and it has to be a crap load, i believe around 4

 

[ApacheXMD]

tikwanleap's right.
Physics dont' lie man.

Under constant acceleration this is 100% correct; however, this is most likely not true. At certain points, such as at the beginning, it's probably higher then it plateaus toward the end.

1.37 wouldn't surprise me, though. 1G is quite a lot. Try falling 100ft, it really feels like you're moving.

100 G's!?!? Wouldn't your body flatten like a pancake at 100G's? Or your eyeballs would pop out of the BACK of your skull. Maybe I'm confused but I thought fighter plane pilots had to be trained to handle like 4-5 G's.

Not Enough

At 100g's you would be going a little over 3,900 m/s. (assuming it was a sustained 100G's.) or roughly 8,700 MPH. You would also be a 1/2" thick film on the back of the seat.

thats cortrrect. the human body can onlt take like 8-10 G MAX you wil DIE at more then that cause teh force will stop your blood from flowing

He is right.

 

[RyanM]

It's gotta be more than 1.3 G's.

I know this for a fact, because I was a Rollercoaster Tycoon, and even some of the more tame rides I built were upwards of 6 G's.

There's atleast one Russian cosmonaut who experienced just over 20Gs during I believe a re-entry accident of some sort...I'll look it up.

What are you smoking???

100 Gs and you would be dead....

Most people will black out at 7-8 Gs (positive), excessive negative Gs will cause a red out.

 

I hope you all learned a valuable lesson.

Hey, I just didn't feel like doing the math and I knew someone would do it for me !

Once again, 1.37 is the average acceleration during the run. At any point in time, especially at the beginning, it may be more than that. 4+G's is most probably only an acceleration spike. Just stating 4+G's actually tells you NOTHING. It could last 4s, it could last .000001s. Stating overall average acceleration gives you a much better picture.

Note: This is assuming the ride goes 0-120mph in 4s

 

[plyons]

Couple of things going on here...

First of all, the average acceleration calculations are correct (I get 1.36 g's due to forward acceleration). You can verify this by simply typing on 120 mph in 4 seconds into Wolfram Alpha.

However, this is just the forward acceleration needed to get you up to speed. The motion of the car (and you) at that point is very much forward. But you need to go UP. The turn in the track as it moved to a nearly(?) vertical incline is what induces the additional g forces. These are likely much higher than those you encounter on the actual acceleration. You will probably feel more pinned to the bottom of your seat as you begin the incline than you did to the back of the seat as you were initially accelerated.

Thus, the unsourced (link broken) claim of 4.0 g's.
