To withstand "g-forces" of up to 10 g's, caused by suddenly pulling out of a steep dive, fighter jet pilots train on a "human centrifuge." 10 g's is an acceleration of 98m/s2. Part A If the length of the centrifuge arm is 10.0 m, at what speed is the rider moving when she experiences 10 g's?

31.3 m/s

Explanation:

Centripetal acceleration = v² / r where r is the length of the arm of the chair

98 m/s² = v² / r

v² = √ (98 m/s² * 10) = 31.3 m/s
