Since astronauts in orbit are apparently weightless, a clever method of measuring their masses is needed to monitor their mass gains or losses to adjust diets. One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 57.5 N is exerted and the astronaut's acceleration is measured to be 0.880 m/s2. Calculate her mass (in kg). kg By exerting a force on the astronaut, the vehicle which they orbit experiences an equal and opposite force. Discuss how this would affect the measurement of the astronaut's acceleration. Propose a method in which recoll of the vehicle is avoided.
