Astronuts in orbit have an apparent weight of zero so they tend to lose bone density and muscle mass over time. Monitnoring body mass is an important part of an astronaught's health care regimine, but they con't simply measure their weight in a scale in order to calculate mass. instend a known foce can be exerted on then while measuring their accelertion, and mass can be calculated. At the start of a long stay in the space station a 55 kg astonaugt sprays air from perssurized canister and accelerates at 0.35 m/s/s. what is the force (thrust) provided by the cansiter? ___________ N Six weeks later the astronaught uses the same canister with the same pressure and accelerates at 0.38 m/s/s. What is the astonaguht's new mass(to two significant figures)? ________ kg
