A weather vane initially at rest has a moment of inertia of 0.113 kg · m2 about its axis of rotation. A 46.0 g piece of clay is thrown at the vane and sticks to it at a point 14.5 cm from the axis. The initial velocity of the clay is 11.5 m/s, directed perpendicular to the vane. Find the angular velocity of the weather vane just after it is struck.

    Consider a turntable to be a circular disk of moment of inertia 0.142 kg⋅m2 rotating at a constant angular velocity 4.80 rad/s2 around an axis through the center and perpendicular to the plane of the disk (the disk's "primary axis of symmetry"). The axis of the disk is vertical and the disk is supported by frictionless bearings. The motor of the turntable is off, so there is no external torque being applied to the axis. Another disk (a record) is...
