Yes, everything in the shop is marked down 25 percent some articles even more.

It's 5.50, reduced from 6.95. It's a real bargain.

Speed, speed!

Speed, François! Speed!

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

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

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

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

The first stage operated at lower voltage and provided the energy for the second stage to spark at a higher voltage.

A reduced daily MSA rate of 43 is applied accordingly.

Well the velocity is just, what's velocity?

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

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

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.

So these two terms this term and this term will simplify to 1 2 Vi, 1 2 the initial velocity plus 1 2 times the final velocity.

It is our final vertical velocity, minus our initial vertical velocity.

IS THE FlNAL VELOClTY INlTIAL VELOClTY OVER TWO.

Now, since the velocity is changing, we're going to say the average velocity.

The average velocity is just the average of the initial velocity and the final velocity.

NOW ONCE AGAlN, WE KNOW THAT INlTIAL VELOClTY IS ZERO, SO OUR CHANG IN VELOClTY IS SAME AS FlNAL VELOClTY

Speed is the magnitude of velocity. It doesn't take into account the direction.

The ratio of the horizontal speed versus the vertical speed gives the same answer.

So the speed is equal to the angular velocity times r

And what we're gonna see in a second is how average speed is different than instantaneous speed.
