A disk is initially at rest. A penny is placed on it at a distance of 1.6 m from the rotation axis. At time t = 0 s, the disk begins to rotate with a constant angular acceleration of 1.5 rad/s2 around a fixed, vertical axis through its center and perpendicular to its plane. Find the magnitude of the net acceleration of the coin at t = 1.3 s.
