A measurement taken from the UW Jacobson Observatory (Latitude: 47.660503°, Longitude: -122.309424°, Altitude: 220.00 feet) when its local sidereal time is 120.00° makes the following observations of a space object (Based on Curtis Problems 5.12 + 5.13): Azimuth: 225.00° Azimuth rate: 2.0000°/s. Elevation: 75.000° Elevation rate: -0.5000°/s Range: 1500.0 km Range rate: -1.0000 km/s a. What are the r & v vectors (the state vector) in geocentric coordinates? (Answer r = [-2503.47 v = [17.298 4885.2 5.920 5577.6] -2.663]) b. Calculate the orbital elements of the satellite. (For your thoughts: what type of object would this be?)

- Two ice skaters, both of mass 68 kgkg, approach on parallel paths 1.6 mm apart. Both are moving at 3.0 m/sm/s with their arms outstretched. They join hands as they pass, still maintaining their 1.6 mm separation, and begin rotating about one another. Treat the skaters as particles with regard to their rotational inertia. a) What is their common angular speed after joining hands? Express your answer in radians per second. b) Calculate the change in kinetic energy for the process described in a). Express your answer with the appropriate units. c) If they now pull on each other’s hands, reducing their radius to half its original value, what is their common angular speed after reducing their radius? Express your answer in radians per second. d) Calculate the change in kinetic energy for the process described in part c). Express your answer with the appropriate units.arrow_forwardPlease solve and explainarrow_forwardNo Chatgpt pleasearrow_forward
