|Centrifuges are used to accelerate a variety of objects, including human test subjects. After the centrifuge reaches a set speed, the test subject moves with uniform circular motion so that the acceleration is centripetal. A centrifuge is used by NASA to measure the effects of great acceleration on human subjects. Once it is up to speed, this centrifuge rotates at a rate of 30 revolutions/minute and has a radius of 10 m. Find the centripetal acceleration of the human test subject. Here, assume the frequency and radius are both given to one significant figure. If needed, the constant 7 may be approximated as T = 3 and the constant g may be approximated as g= 10 m/s², both to one significant figure.
