A large clock has a second hand with a mass of 0.10 kg concentrated at the tip of the pointer.
(a) If the length of the second hand is 30.0 cm, what is its angular momentum?
(b) The same clock has an hour hand with a mass of 0.20 kg concentrated at the tip of the pointer. If the hour hand has a length of 20.0 cm, what is its angular momentum?
