Two objects on a turntable spin at a constant rate. What (if anything) is the same for the two objects?

1. They have the same speed, but different velocities.
2. They have the same speed and the same velocity.
3. The have the same angular speed, but different angular velocities.
4. They have the same angular speed and the same angular velocity.
5. None of the above.

What about their accelerations?

1. Their tangential accelerations have the same magnitude, but the red one has a larger angular acceleration.
2. Their tangential accelerations have the same magnitude, but the blue one has a larger angular acceleration.
3. Both the tangential acceleration and the angular acceleration equal zero for both objects.
4. None of the above.
