Hurry up, it's late.

By itself, it's one of the fastest circuits in the world.

And fast.

I'll specify that by v I want to be clear. This is not vector quantity.

So it's the 80 minus the velocity of B is equal to 40 meters per second.

Betty's velocity let's just do it that way if we divide both sides by 20 we get 3 2 of Betty's velocity is equal to Ann's velocity.

The choice in this case is pretty simple.

Ahead full, sir. Engines report ahead full.

Tony is a fast runner.

To get on it's very low bandwidth, and also it spreads information very quickly.

Okay, everyone

This will be quick.

So from this guy's point of view, this train is approaching with the velocity let me do, is approaching with the velocity vA plus vB.

And the distance that Bill went in 6 minutes is velocity of Bill times 6.

Do you swim very fast, too?

You only need 70.

This time becomes below a microsecond.

And for those of you who prefer miles per hour, that's over 45 miles per hour in water.

And let me plot its velocity against time so this is my velocity

If we subtract 400 from both sides, we get 12 times

Divide both sides of this equation by 12.

You get minus velocity of B is equal to minus 40.

Your mind can process a facial expression in 33 milliseconds. It can move pretty damn quick.

So let's say that Ann is traveling with velocity A and Betty is traveling with velocity B.

You get Chelsea's velocity is equal to Alice's velocity minus 400 12.

So it's 3 times 10 to the eighth meters per second.

So what's the actual distance she traveled?

And we could say x is equal to acceleration.

And then we get the hottest links on Reddit.

We know it in terms of Ann's velocity.

Naoko is a fast runner.

Please send it by special delivery.

I am the fastest runner.

A soft wind is blowing. The cloud is moving slowly.

Come on, fucking fastball.

No, we speed them up, don't we? So we used to dial now we speed dial.

It's growing fast.

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

Thrun The next concept I'd like to teach you is called D separation.

So who's left is on top of the food chain.

So you end up getting omega times r meters per second

Let's think of the speed of a...

So what's the distance that Alice travels in 6 minutes?

The call came from a highway rest stop, southbound side. Yeah.

And if you remember the idea of slope from your Algebra 1 class that's exactly what acceleration is, in this diagram right over here
