A uniform circular metal disk has radius 36 cm and mass 350 g and its center is at the origin. Then a circular hole of radius 9 cm is cut out of it. The center of the hole is a distance 13.5 cm from the center of the disk. The disk is rotating at a rate of 3.3 rad/sec.

1) What is the moment of inertia of the modified disk about the origin?

2) What is the total linear velocity of a piece metal at the disk's outer edge?

3) What is the total linear velocity of a piece metal 7.5 cm from the center?

4) What is the total linear acceleration of a piece metal at the disk's outer edge?

5) What is the total linear acceleration of a piece metal 7.5 cm from the center?
