1.14 In an experimental test, a spacecraft in circular orbit around the Earth carried an accelerometer that was placed at a distance of 2 m from the center of mass (see Fig. 1.21). The acceleration measured by the accelerometer was 10-6 m/s² with the spacecraft oriented as shown in the figure. AY (a) What was the radius of the orbit? Assume that the spacecraft was not rotating relative to the fixed stars. (b) Explain how the output from several such accelerometers, placed at different points in the spacecraft, could be used to determine the orientation of the spacecraft relative to the Earth.
