I DON'T KNOW WHAT IM DOING WRONG!!!!!!NASA has built centrifuges to enable astronauts to train in conditions in which the acceleration is very large. The device in the figure below shows one of these "human centrifuges." If the device has a radius of 8.3 m and attains accelerations as large as 5.1 g, what is the rotation rate?

v=20.377
c=52.15
rotation rate = 2.55 ITS WRONG what am I doing WRONG????

    I have no idea what you did.

    5.1*9.8m/s^2=w^2*radius

    w= sqrt (5.1*9.8/8.3) in radians/sec
