1. The angular acceleration of the disk is defined by a = 3t2 + 12 rad> s, where t is in seconds. If the disk is originally rotating at v0 = 12 rad> s, determine the magnitude of the velocity and the n and t components of acceleration of point A on the disk when t = 2 s.

2. The disk is originally rotating at v0 = 12 rad> s. If it is subjected to a constant angular acceleration of a = 20 rad> s2, determine the magnitudes of the velocity and the n and t components of acceleration of point A at the instant t = 2 s.

3. The disk is originally rotating at v0 = 12 rad> s. If it is subjected to a constant angular acceleration of a = 20 rad> s2, determine the magnitudes of the velocity and the n and t components of acceleration of point B when the disk undergoes 2 revolutions.
