The angular displacement of the centrifuge is given by e = 4.7[t + 33e-(0.030t) - 33] rad, (here -33 is not in the power only -0.030 is in the power) where t is in seconds and t = 0 is the startup time. If the person loses consciousness at an acceleration level of 10.5g, determine the time t at which this would occur. Verify that the tangential acceleration is negligible as the normal acceleration approaches 10.5g.

Don't give the same answer I will downvote pls I want correct
The angular displacement of the centrifuge
is given by 0 = 4.7[t + 33e-(0.030t) - 33] rad,
(here -33 is not in the power only -0.030 is in
the power) where t is in seconds and t = 0 is
%3D
the startup time. If the person loses
consciousness at an acceleration level of
10.5g, determine the time t at which this
would occur. Verify that the tangential
acceleration is negligible as the normal
acceleration approaches 10.5g.
