And you would say, it takes 15 seconds.

You get vbt minus vct is equal to 300.

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

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 in 5 seconds and they give us that information.

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

Although I'm sure you know this formula.

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

So this goes straight back to the, the standard to distance is equal to rate times time.

At our current speed, 8.2 hours.

They just said that the officer is going 3 times as fast, but we don't know absolute velocities.

So maybe I go, every half second so on this half second, I was going at this velocity and I go at that velocity for half a second velocity times the time will give me the displacement and then I do it for the next half second same exact idea here, it'll give me the displacement so on and so forth

So what is the actual distance?

She's going at the same velocity, but it takes her 20 minutes.

The train ran at the rate of 500 miles an hour.

The train was going 500 miles per hour.

The train was moving at 500 miles per hour.

And this key word average is interesting.

Average goes to 23.5 miles per hour.

Average foot speed over uneven ground, barring injuries, is four miles per hour.

Acceleration time

Appearance time

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

OK, so let's put in some numbers.

That's how fast he's approaching the back of the column.

So the slope over here might be 23... whatever miles per hour, but instantaneous, his fastest poin in this 9.58 seconds is closer to 30 miles per hour.

When the girl at rest, velocity equals zero miles per hour, begins accelerating to reach the speed within seconds, velocity increases rapidly to 25,000 miles per hour, her brain would crash into the side of her skull.

Time to the front.

With 1425 meters elevation the air is getting thinner

In the case of Usain Bolt how fast is he going right now?

But this inward force of gravity is going to accelerate this object inwards while it travels.

So, an object will continue moving or staying at the same place unless something changes it.

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

Divide both sides of this equation by 12.

We expect that x prime will be composed of our old position plus whatever motion was occurring due to the velocity.

100 metres. and so using this information we can actually figure out his average speed his average speed right this way his average speed is just going to be change in distance over his change in time and using the variable over here we are saying y is distance and this is change in y over change in x from this point to that point and this might look somewhat familiar to you from basic algebra.This is the slope between two points.

I must make up for lost time by driving fast.

The amplitude is simply telling you how well aligned you are, it doesn't say anything about lenses.

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

And what's the distance that he travels in that same amount of time?

So instead of that, what we do is, we do, we transform coordinates.

But as this ring rotates at about 1,700 rpm that's 28 times per second.
