Question

Topics and skills: Vectors, calculator Two tracking stations make a sighting of a UFO. Seven seconds later both tracking stations make another sighting of the UFO. Based on these two sightings, the position and velocity of the UFO are determined. One second after the second sighting, a probe is launched at precisely the correct speed and heading to in UFO. How is it done? Measuring all distances in meters, Figure 1 shows the coordinates and the horizontal locations of the tracking stations and the launch site. The elevations are given by the third coordinates. Table 1 shows the bearings of the UFO taken by the tracking stations in each of two sightings. For example, tracking station 1 first sights the UFO at 30 degree south of due west at an angle of 0.83 degree above the horizontal. (Note that the stations are on hills.) Now assume (a major assumption) that the UFO travels on a straight line between P_1 and P_2 at a constant speed. Find an equation of the line on which the UFO travels. Call the equation of this line r(t), for t greaterthanorequalto 0. where t = 0 is the time of the first sighting. Knowing that seven seconds pass between the first and second sightings, what is the speed of the UFO? The equation of the line on which the UFO travels in Step 7 is not unique. Adjust the equation of the line so that the speed of the UFO equals the speed found in Step 8. Call the equation of this line r(t), for t greaterthanorequalto 0.
