Question

Pilots and astronauts are tested for the stresses of flying high-speed aircraft in a spinning "human centrifuge", a device which spins at high speed to simulate the effects of high accelerations. If the device, starting from rest, takes 2.4 minutes to turn through 33 complete revolutions before reaching its final speed, what was its angular aceleration (assumed constant)?

For the "human centrifuge" described in the previous problem, what is its final speed, expressed in rpm? [no units are required]?

Explanation / Answer

[ w + 0 ]/2 * 2.4 * 60 = 33 * 2 pi w = 2.87 rad per s 2.87 = 0 + a * [ 2.4 * 60 ] a = 0.01999 rad /s^2
