Question: The angular acceleration of the disk is defined by = 3t 2 + 12 rad/s, where t is in seconds. If the disk is

The angular acceleration of the disk is defined by α = 3t² + 12 rad/s, where t is in seconds. If the disk is originally rotating at ω₀ = 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.
