The rigid body rotates about the z axis with counterclockwise angular velocity ω = 4 rad/s and counterclockwise angular acceleration α = 2 rad/s2. The distance rA/B = 0.6 m.

(a) What are the rigid body’s angular velocity and angular acceleration vectors?

(b) Determine the acceleration of point A relative to point B, first by using Eq. (17.9) and then by using Eq. (17.10).
