1. The problem statement, all variables and given/known data

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 with a non-zero angular acceleration. For each of the following statements select the correct option to complete the statement.

Each of these statements have variables that are underlined

1. For a given time, mass 2 travels a distance that is less than the distance traveled by mass
2. The magnitude of the total acceleration of mass 1 is greater than the total acceleration of mass.
3. For a given time, the angle covered by mass 2 is equal to the angle covered by mass 1.
4. For a given time, the angle covered by mass 2 is equal to the angle covered by mass 1.
5. The angular acceleration of mass 2 is equal to the angular acceleration of mass 1
6. The centripetal (radial) acceleration of mass 2 is less than the centripetal acceleration of mass 1.
7. The tangential acceleration of mass 2 is equal to the tangential acceleration of mass 1.

2. Relevant equations

ac=v2/r
T=(2$\pi$)/ω

3. The attempt at a solution

I tried using the relevant equations to prove these statements but it didn't work. I'm not sure which statement is false, or if there's more than 1 wrong statement.
