The average velocity is just the initial velocity plus the final velocity over 2.

IS THE FlNAL VELOClTY INlTIAL VELOClTY OVER TWO.

Whereas now, second gear it's like Africa had first gear, now they go into second gear.

Speed, speed!

VELOClTY DlVIDED BY TWO.

We know the average velocity is equal to the final velocity plus the initial velocity over 2, and this assumes acceleration is constant.

FlNAL VELOClTY SQUARED, FlNAL VELOClTY TlME FlNAL VELOClTY

So no matter what your upward velocity, the time in the air is going to be your speed, your vertical speed, divided by the acceleration of gravity.

Speed, François! Speed!

We know the change in distance divided by the change in time is equal to velocity average velocity, and it would equal velocity if velocity's not changing, but average when velocity does change and we have constant acceleration, which is an important assumption.

CHANGE IN VELOClTY IS THE SAME THlNG AS FlNAL VELOClTY MlNUS INlTIAL VELOClTY

The height here is my final velocity minus my initial velocity.

Vi plus Vf (No that's not the right color)

The hospital is calling for her most urgently.

The initial velocity, plus, now the final velocity is now the initial velocity, plus acceleration times time, and then we divide all of that by 2 times time.

Well the velocity is just, what's velocity?

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

So, here's speed and velocity, but let's just do one thing at a time.

YOU WlLL GET, AND I FLlP THEM AROUND, FlNAL VELOClTY IS EQUAL TO

Well, the velocity is equal to distance divided by time.

And to figure out the velocity, we just divide her momentum by her mass.

But you have to keep your speed up.

We know also that velocity, or let's say the change in velocity, is equal to the final velocity minus the initial velocity.

Assuming that we start with... so my initial velocity, or I could say the magnitude of my initial velocity so just my initial speed, you could say, this is just a fancy way of saying my initial speed... ...is zero

Our speed, what they want us to figure out is going to be equal to or maybe I should write it as our speed at time 3

If we know the initial velocity, acceleration, and the distance, and we want to figure out the final velocity, we could use this formula vf squared equals vi squared plus 2a times really the change in distance, so I'm going to write the change in distance, because that sometimes matters when we're dealing with direction change in distance, but so you'll sometimes just write this as distance.

It's not the velocity. It's the magnitude of velocity

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

So this is the velocity.
