Slowing down.

Slowing down?

Acceleration time

Appearance time

With 1425 meters elevation the air is getting thinner

Launch coming up off the stern, sir. Half speed.

Decelerate.

Decelerate.

Uh, 48 hours and counting.

And what I want to show you in this video that is in general, if you plot velocity, the magnitude of velocity ...so you could say speed versus time... or let me just stay with the magnitude of the velocity versus time the area under that curve is going to be the distance traveled (or the displacement) because displacement is just the velocity times the change in time so if you just take out a rectangle right over there

And you would say, it takes 15 seconds.

They're slowing down.

So, we went down actually.

You get vbt minus vct is equal to 300.

We should take our foot off the pedal right now, and generally we do.

Now let's go back to the other problem.

I was thinking maybe you should spend a little less time

Slow us down.

They've dropped to impulse.

The Spider's slowing!

Slow the car down.

And in 5 seconds and they give us that information.

This is close to but does not have to be equal to the age of the Universe at that time, T0.

They're full of nitrogen.

The choice in this case is pretty simple.

It is probable that he may spend little time there in the future.

So the column will move its distance is equal to the column's rate, velocity.

Come on. Decelerate!

the light's red.

Although I'm sure you know this formula.

We've broken the light barrier 22 hours early.

So when the linkage parted, it went the other way. Up instead of down.

Running a little hot. Want to open up a speed brake?

They become rarer because we fish them.

All hands squared away to decelerate.

Don't slow down.

So, you know, even sex is on a stopwatch these days.

From this point, we're going to decelerate from 12,500 miles an hour down to 900 miles an hour.

I probably can't do both.

All right. We're down to 0.3896 of light speed.

So we say 84 is equal to velocity times your initial velocity times time.

Let's say we know that it's time, t.

Arnold, we're going to hit light speed in 24 hours,

I'm like, Okay, all right, this guy is slowing down,

By the time we see what is ahead of us and react to it time times velocity equals distance equals one fifth of a second times 25,000 miles per hour equals 1.4 miles
