The minute and hour hands of a clock have a common axis of rotation and equal mass. the minute hand is long, thin, and uniform; the hour hand is short, thick, and uniform. is the moment of inertia of the minute hand greater than, less than, or equal to the moment of inertia of the hour hand?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
