1) Hickory dickory dock, the 20.0-g mouse ran up the clock, and took turns riding on the 0.20-m-long second hand, the 0.20-m-long minute hand and the 0.10-m-long hour hand. What was the angular momentum of the mouse on each of the three hands?
2) In a physics experiment, Ingrid, the ice skater, spins around in the rink at 1.2 m/s with each of her arms stretched out 0.70m from the center of her body. In each hand she holds a 1.0kg mass. If angular momentum is conserved, how fast will
