Final answer:
The astronaut's tangential speed when the space station is operating properly is approximately 0.447 m/s.
Step-by-step explanation:
To calculate the astronaut's tangential speed when the space station is operating properly, we need to find the angular velocity of the station. The formula to calculate angular velocity is:
ω = √(g / r)
where ω is the angular velocity, g is the artificial gravity (9.80 m/s²), and r is the radius of the station (75.3 m). Plugging in the values, we get:
ω = √(9.80 / 75.3)
Calculating this, the astronaut's tangential speed is approximately 0.447 m/s.
