32 ft/s/s

Time Distance Speed average speed

1 s----16 ft----32 ft/s---16 ft/s

2 s----64 ft----64 ft/s---48 ft/s

3 s---144 ft----96 ft/s---80 ft/s

4 s---256 ft---128 ft/s--112 st/s

So at about 240 ft traveled the object would be traveling 124 ft/s

124 ft/s x 60 sec/min x 60 min/hr

--------------------------------------- = 84.5 MPH

5280 ft/mile

I can't see how what other people do in their spare time affects you in any way...

Physics is a major part of my job and it lets me understand my hobbie alot more than people who have a life.

Before you can have any fun on a coaster there are some people who sit in front of a computer without a life who use physics to calculate the forces exerted on a rider and the limits it can obtain. So that after riding a coaster you literally have a life.

"On The Eigth day they made Coasters"

Let me guess that would mean that "They" need to get a life?

I would have posted it there if it wouldn't have been closed.

V [mph] = 60/11 * sqr(h[feet])

As for where that comes from...

` `

A = V' = D'' = 32 ft/sec/sec.

V = At + V0 = 32t ft/sec + 0 ft/sec = 32 ft/sec.

D = 1/2At^2 + V0t + D0 = 1/2At^2+0t+0 feet

= 16t^2 feet

Now, since we know the distance, we can rearrange and substitute as follows:

` `

t = sqr(d)/4 seconds

v = 32 sqr(d)/4 feet per second

Given a 240 foot fall...

` `

t = sqr(240)/4 = 3.8729833462 seconds

v = 32 sqr(240)/4 = 123.935467078 feet/second

Multiply by 3600 seconds/5280 feet and get...

`84.5014548259 mph`

To generalize, let's go back to the velocity equation:

` `

v = 32 feet * sqr(h)/4 seconds * 3600 seconds/5280 feet

v = (115200/21120) * sqr(h) miles per hour

v = (60/11) * sqr (h) miles per hour

What is the Average Speed of the Millennium Force from point A, located at the top of the lift to point B, located at the first break?

I am willing to bet that the Force WASTE all other (complete circuit) coasters in this category.

To do this we need the distance between B and A and the time it takes the train to travel between A and B. I can talk with Pythagorus and get the length of the lift, but I don't know the length of the brake run and Station, nor the time it takes for the train to get from A to B.
