Problem 3 A 60.0-kgrunner runs clockwise around the edge of a horizontal turntable mounted on a vertical, frictionless axis through its center. The runner's velocity relative to the ground has magnitude 2.00 m/s. The turntable is rotating in the opposite direction (counterclockwise) with an angular velocity of magnitude 0.300 rad/s relative to the ground. The radius of the turntable is 2.90 m, and its moment of inertia about the axis of rotation is 80.0 kg m2. Questions 4 and 5...

A barbell consists of two small balls, each with mass 500 grams
(0.5 kg), at the ends of a very low mass rod of length d= 20 cm
(0.2 m). The center of the barbell is mounted on the end of a low
mass rigid rod of length b= 0.3 m (see Figure). The apparatus is
started in such a way that although the rod rotates clockwise with
angular speed 80 rad/s, the barbell maintains its vertical
orientation.
