Telstar #1
Calculate where to put aconmunications  satellite so it will be above the same point above the earth all the time.  Geosynchronous Orbit!


The little satellite that could!!!

America’s Defence Meteorological Satellite Programme (DMSP), which has overseen the construction of eight F-series satellites that use microwaves sensors to monitor sea-ice coverage. These probes, which have lifespans of three to five years, have shown that millions of square kilometres of sea ice have disappeared from the Arctic over the past 20 years, allowing less solar energy to be reflected back into space – and so further increasing global temperatures – while also disrupting Inuit life and wildlife in the region.

At present three ageing satellites – DMSP F16, F17 and F18 – remain in operation, though they are all beginning to drift out of their orbits over the poles. The latest satellite in the series, F19, began to suffer sensor malfunctions last year and finally broke down a few weeks ago. It should have been replaced with the F20 probe, which had already been built and was being kept in storage by the US Air Force. However it had to be destroyed, on the orders of the US Congress, on the grounds that its storage was too costly.

Any guess on the cost to build a new satellite?

The radius of the Earth!

Measurement of the Earth's circumference[edit]

Illustration showing a portion of the globe showing a part of the African continent. The sunbeams shown as two rays hitting the ground at Syene and Alexandria. Angle of sunbeam and the gnomons (vertical pole) is shown at Alexandria, which allowed Eratosthenes' estimates of radius and circumference of Earth.

Eratosthenes calculated the circumference of the Earth without leaving Egypt. He knew that at local noon on the summer solstice in Syene(modern Aswan, Egypt), the Sun was directly overhead. (Syene is at latitude 24°05′ North, near to the Tropic of Cancer, which was 23°42′ North in 100 BC^[16]) He knew this because the shadow of someone looking down a deep well at that time in Syene blocked the reflection of the Sun on the water. He measured the Sun's angle of elevation at noon on the same day in Alexandria. The method of measurement was to make a scale drawing of that right triangle with the vertical rod and its shadow as its legs and to measure the acute angle subtending to the shadow. This turned out to be about 7°, or 1/50th of the way around a circle. Taking the Earth as spherical, and knowing both the distance and direction of Syene, he concluded that the Earth's circumference was fifty times that distance.

• KPSS:
• Divide problem into 2 separate problems 1 in the x and 1 in the y
• Relate the motion, position, velocity and accelerations of each by the time.
• Keep in mind that you are solving for the vector components and must recombine the X&Y to get a final answer 
• Sample Problem 1 "Outfoxed"  put in your notebook
•  ( Note this includes a before and after)
• Sample Problem 2 "Moon Shot" put in your notebook

After studying the material of this chapter, you should be able to:
1. Represent the magnitude and direction of a vector using a protractor and ruler.
2. Multiply or divide a vector quantity by a scalar quantity.
3. Use the methods of graphical analysis to determine the magnitude and direction of the vector resultant in problems involving vector addition or subtraction of two or more vector quantities. The graphical methods to be used are the parallelogram method and the tip to tail method.
4. Use the trigonometric component method to resolve a vector components in the x and y directions.
5. Use the trigonometric component method to determine the vector resultant in problems involving vector addition or subtraction of two or more vector quantities.
6. Use the kinematics equations of Chapter Two along with the vector component method of Chapter Three to solve problems involving two dimensional motion of projectiles.
