BIO Dizziness. Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness. Suppose that a skater is spinning very fast at 3.0 revolutions per second about a vertical axis through the center of his head. Take the inner ear to be approximately 7.0 cm from the axis of spin. (The distance varies from person to person.) What is the radial acceleration (in m/s2 and in g’s) of the endolymph fluid?

in the inner ear. Spinning displaces this fluid, causing dizziness.
Suppose a dancer (or skater) is spinning at a very fast 2.7
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.
