Conceptual - Angular Rotation
Two objects of equal mass are on a turning wheel. Mass 1 is located at the rim of the wheel while mass 2 is located halfway between the rim and the axis of rotation. The wheel is rotating at a constant angular velocity. For each of the following statements select the correct option.
Greater Than: The radial acceleration of mass 1 ____ the radial acceleration of mass 2.
Equal To: The tangential acceleration of mass 2 ____ the tangential acceleration of mass 1.
Less Than: For a given time, mass 2 travels a distance ____ mass 1.
Greater Than: The speed of mass 1 is ____ mass 2.
Equal To: For a given time, the angle covered by mass 2 is ____ mass 1.
Less Than: The moment of inertia of mass 2 is ___ the moment of inertia of mass 1. (Both moments of inertia are taken about the axis of rotation.)
Greater Than: The radial acceleration of mass 1 ____ the radial acceleration of mass 2.
Equal To: The tangential acceleration of mass 2 ____ the tangential acceleration of mass 1.
Less Than: For a given time, mass 2 travels a distance ____ mass 1.
Greater Than: The speed of mass 1 is ____ mass 2.
Equal To: For a given time, the angle covered by mass 2 is ____ mass 1.
Less Than: The moment of inertia of mass 2 is ___ the moment of inertia of mass 1. (Both moments of inertia are taken about the axis of rotation.)

can someone please let me know which ones i got wrong. i
cant seem to figure this one out. thanx
For a given time, mass 2 travels a distance LESS THAN mass 1.
The tangential acceleration of mass 1 GREATER THAN the
tangential acceleration of mass 2.
For a given time, the angle covered by mass 2 is EQUAL TO
mass 1.
The moment of inertia of mass 2 is LESS THAN the moment of
inertia of mass 1. (Both moments of inertia are taken about
the axis of rotation.)
The radial acceleration of mass 1 LESS THAN the radial
acceleration of mass 2.
The speed of mass 1 is EQUAL TO mass 2.
