Question

Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness. Suppose a dancer (or skater) is spinning at a very fast 2.8 revolutions per second about a vertical axis through the center of his head. Although the distance varies from person to person, the inner ear is approximately 7.0 cm from the axis of spin.

Part A

What is the radial acceleration (in m/s2) of the endolymph fluid?

Express your answer with the appropriate units.

Part B

What is the radial acceleration (in g's) of the endolymph fluid?

Express your answer as a multiple of g.
