A disk of radius 50 cm rotates about an axis passing through its center and perpendicular to its plane. The angular position of a point on the disk is given by 0 = 2.0 + 4.0t² + 2.0t³, where 0 is in radians and t is in seconds. What is the magnitude of the total linear acceleration of a point on the disk that is 40 cm from the center at time t = 0.25 s?
