A centrifuge training model checks acceleration from spin rate and radius. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Spin rate and radius set acceleration
The checked spin-rate scalar is 2 per second and the radius is 3 m.
u=2per s,r=3m
Acceleration is rate squared times radius
The training acceleration is 12 metres per second squared. Real RPM conversion factors are outside this model.
