1.      (5 points) Record the position of the satellite

Go to http://science.nasa.gov/temp/NOAA12Loc.html, it will update every minute, and
then record between eleven and fifteen consecutive samples. Again, this must be done
every minute!

Time                   Latitude                 Longitude             Altitude
(hours:minutes)            (degrees)                 (degrees)           (kilometers)

2.      (10 points) Distance traveled in each minute:

Go to http://www.indo.com/distance/, and enter the latitude and longitude of the first data
point into the from box, and then record the latitude and longitude of the next data point
into the to box. You’ll need to repeat this for each consecutive pair. For example if the
latitude is 15 and the longitude as -11, you would type 15N 11W; or if the latitude is -13
and the longitude as 19, you would type 13S 19E.

Time            Latitude       Longitude        Altitude     Earth Distance     Satellite Distance
(hrs:min)        (degrees)       (degrees)          (km)             (km)                (km)

3.      (5 points) Calculate the orbital radius of the satellite:

4.      (10 points) Calculate the average speed and the period of rotation.
5.      (10 points) Displacements, elapsed time and central angle

Distance to
Time      Latitude    Longitude     Altitud                    elapsed     Central Angle
Point                                                      center point
(hr:min)    (degree)    (degree)      e (km)                     time (s)    (radians)
F (km)

6.      (5 points) Calculate the acceleration

7.      (10 points) Draw a vector diagram indicating your initial and final velocities and the
acceleration.
