Explanation:
Answer:
Mass of astronaut will be 119.7674 kg
Explanation:
We have given mass of the chair
When there is chair alone then time period of osculation
Now when astronaut sit on the chair then total mass
Now with astronaut time period is
For spring time period is given by
So
Squaring both side
Mass of astronaut will be 119.7674 kg
