Question

A centrifuge consists of a chamber (in which the astronaut sits) that is fixed to the end of a long horizontal and rigid pole. The arrangement is rotated about an axis perpendicular to the pole's free end. Such a centrifuge starts from rest and has an angular acceleration of 0.25 rad/s^2. The chamber is 3.0 m from the axis of rotation. Through what angle has the decive rotated when the centripetal acceleration experienced by an astronaut in the chamber is four times the acceleration due to the earth's gravity?

Explanation / Answer

Given centripetal acceleration= 4g
r2 = 4g

s0 = 3.61 rad/sec

We know

2 = 2

so = 2 / 2 = 26.1 rad
