A toy is designed so that when charged it stores rotational energy on a spherical ball of diameter 60 mm and mass 890 g distributed uniformly. The ball is pivoted using a frictionless axle passing through its center. A dent on the toy's body scratches the ball at a point on its center creating 0.0820 N friction force at the point of contact. Determine the angular acceleration of the ball.
