Connecting Linear and Rotational Motion Practice Test

A ceiling fan blade rotates with angular speed $\omega$. Point $M$ is located near the hub and point $N$ is at the tip, farther from the axis. Consider the fan at an instant when it is spinning steadily. Which statement correctly compares the magnitudes of the points’ centripetal accelerations?

A carousel rotates at constant $\omega$. Rider A sits at radius $r$ and rider B at radius $3r$. Which compares the magnitudes of their tangential accelerations?
