Astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. The Body Mas

anzhelika [568]

Answer:

55 kg

Explanation:

spring constant (k) = 600 N/m

mass of chair (Mc) = 12 kg

period of oscillation of chair and man (T) = 2.1 s

what is the mass of the astronaut (Ma) ?

mass of the astronaut (Ma) = total mass (Mt) - mass of chair (Mc)

where

total mass (Mt) = $\frac{T^{2}}{4π^{2}}k$

taking π as 3.142

total mass (Mt) = $\frac{2.1^{2}}{4 x 3.142^{2}}600$

total mass (Mt) = 67 kg

therefore

mass of astronaut = 67 - 12 = 55 kg
