### Rotation Question

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

- They have the same speed, but different velocities.
- They have the same speed and the same velocity.
- The have the same angular speed, but different angular velocities.
- They have the same angular speed and the same angular velocity.
- None of the above.

What about their accelerations?

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