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 58.0 N is exerted and the astronaut's acceleration is measured to be 0.930 m/s2. Calculate her mass in kilograms.
