A CD with a Diameter Of $12.0 \mathrm{~cm}$ Starts from Rest and with a Constant Angular Acceleration Of Rest

Multiple Choice

A CD with a diameter of $12.0 \mathrm{~cm}$ starts from rest and with a constant angular acceleration of $1.0 \mathrm{rad} / \mathrm{sec}^{2}$ acquires an angular velocity of $5.0 \mathrm{rad} / \mathrm{sec}$ . The CD continues rotating at $5.0 \mathrm{rad} / \mathrm{sec}$ for $15 \mathrm{~seconds}$ and then slows to a stop in 12.0 second with a constant angular acceleration. What is the angular distance traveled by a point $4.0 \mathrm{~cm}$ from the center, at the time 2.0 seconds from the start?

A) $2.0 \mathrm{rad}$
B) $6.0 \mathrm{rad}$
C) $10.0 \mathrm{rad}$
D) $8.0 \mathrm{rad}$
E) $4.0 \mathrm{rad}$
