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 49.0 n is exerted and the astronaut's acceleration is measured to be 0.780 m/s2. calculate her mass in kilograms.
