A horizontal disk rotates about a vertical axis through its
center. Point P is midway between the center and
the rim of the disk, and point Q is on the rim. If
the disk turns with constant angular velocity, which of the
following statements about it are true? (There may be more than one
correct choice.)
The linear acceleration of P is twice as great as the
linear acceleration of Q.
Q is moving twice as fast as P.
The linear acceleration of Q is twice as great as the
linear acceleration of P.
P and Q have the same linear acceleration.
The angular velocity of Q is twice as great as the
angular velocity of P.
