Randall D. Knight — Kinematics in Two Dimensions: Problem Exercise_32

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 $98 \text{ m/s}^2$. If the length of the centrifuge arm is $12 \text{ m}$, at what speed is the rider moving when she experiences 10 g’s?
