As we've seen, astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. the body mass measurement device on skylab, a 1970s space station, had a spring constant of 606 n/m. the empty chair oscillated with a period of 0.848 s. what is the mass of an astronaut who oscillates with a period of 2.26 s when sitting in the chair?

mass of astronaut is M 67.362 kg

Explanation:

Given details:

spring constant k = 606 N/m

Time T = 0.848 s

The time period is

So the mass of the empty chair is

                   = 11.038 kg

When astronaut is sitting in the chair then the time period is

                  m' = 78.40 kg

mass of astronaut is M = m' - m

                                              = (78.40 kg) - ( 11.038 kg)

                                              = 67.362 kg

where is the circuit diagram ?

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
