The angular displacement of the centrifuge is given
by \theta =4[t+30e^(-0.03t)-30]rad, where t is in sec-
onds and t=0 is the startup time. If the person
loses consciousness at an acceleration level of 10g,
determine the time t at which this would occur.
Verify that the tangential acceleration is negligible
as the normal acceleration approaches 10 g .
