Please help!! An astronaut passes out when the centrifuge reaches an acceleration of 12 g. If the centrifuge has
a radius of 11.5 m, at what speed will the astronaut pass out?

Respuesta :

Answer:

the speed of the astronaut is 36.78 m/s.

Explanation:

Given;

centripetal acceleration of the astronaut, [tex]a_c[/tex] = 12 g = 12 x 9.8 m/s² = 117.6 m/s²

radius of the centrifuge, r = 11.5 m

The speed of the astronaut is calculated as follows;

[tex]a_c = \frac{v^2}{r} \\\\v^2 = a_c r\\\\v = \sqrt{a_c r} \\\\v = \sqrt{117.6 \times 11.5} \\\\v = 36.78 \ m/s[/tex]

Therefore, the speed of the astronaut is 36.78 m/s.
