The following questions refer to the second hand of a clock. The rotational inertia of the second hand is I=1/3mL^2, the length of the second hand is L=0.2m, the mass of the second hand is m=0.04kg. a) what is the direction of the angular velocity of the second hand of the clock? b) what is the magnitude of the angular velocity of the second hand of the clock? c) what is the linear speed of the tip of the second hand of the clock? d) what is the angular momentum of the second hand of the clock? e) how many radians does the second hand pass through in 45 seconds?
