Question

1. Since astronauts in orbit are apparently weightien, a clever method of measuring their masses is needed to monitor their man gains or losses to adjust diets. One way to do this is to exert a known force on an astronauts and measure the acceleration produced. Suppose a net external force of 50.0 N is exerted and the astronaut's acceleration measured to be 0.893 m/s

Answer 1

$$m=\frac{F}{a}\\m=\frac{50}{0.893}=56\ kg$$
