A uniform disk of mass Mdisk = 4.7 kg and radius R = 0.22 m has a small block of mass mblock = 2 kg on its rim. It rotates about an axis a distance d = 0.16 m from its center intersecting the disk along the radius on which the block is situated.

a) What is the moment of inertia of the block about the rotation axis?

b) What is the moment of inertia of the disk about the rotation axis?

c) When the system is rotating about the axis with an angular velocity of 4.7 rad/s, what is its energy?

d) If while the system is rotating with angular velocity 4.7 rad/s it has an angular acceleration of 8.6 rad/s2, what is the magnitude of the acceleration of the block?
