A solid cylinder of mass 2.0 kg and radius 20 cm is rotating counterclockwise around a vertical axis through its center at 600 rev/min. A second solid cylinder of the same mass and radius is rotating clockwise around the same vertical axis at 900 rev/min. If the cylinders couple so that they rotate about the same vertical axis, what is the angular velocity of the combination?
A wheel 2.00 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.00 rad/s2. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t = 2.00 s, find (a) the angular speed of the wheel and, for point P, (b) the tangential speed, (c) the total acceleration, and (d) the angular position.
A space station is constructed in the shape of a hollow ring of mass 5.00 104 kg. Members of the crew walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 100 m. At rest when constructed, the ring is set rotating about its axis so that the people inside experience an effective free-fall acceleration equal to g. (See Fig. P10.52.) The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. (a) What angular momentum does the space station acquire? (b) For what time interval must the rockets be fired if each exerts a thrust of 125 N? Figure P10.52 Problems 52 and 54.

A 60.0-kg woman stands at the rim of a horizontal turntable having a moment of inertia of 500 kg m2 and a radius of 2.00 m. The turntable is initially at rest and is free to rotate about a frictionless, vertical axle through its center. The woman then starts walking around the rim clock-wise (as viewed from above the system) at a constant speed of 1.50 m/s relative to Earth. (a) In what direction and with what angular speed does the turntable rotate? (b) How much work does the woman do to set herself and the turntable into motion?

Sphere A, with a mass of m₁ = 3.00 kg and radius of r = 50.0 mm, is initially pushed to the left imparting a linear velocity of v_o 4.00 m/s. The sphere rolls with sliding until time t when it stabilizes and rolls without sliding. The coefficient of sliding friction between the sphere and the floor is µ = 0.250. Assume that the linear and angular acceleration of the sphere is uniformly accelerated before reaching time t. Determine the angular acceleration of the sphere, and the time t at which the sphere will start rolling without sliding.
In the assembly below the system can rotate around the vertical axis. The left part is a square where R = 0.1 meters, and the mass of each of the four thin bars is uniform and is 0.1 kg. On the left is a massive sphere of radius R = 0.2 meters and Mass M = 0.3 kg. Assume that the system rotates with constant period T = 2.0 s, when, without any external action, as three leftmost bars detach from the system, leaving only the right vertical bar (on the axis) and sphere . What will be the new period of system revolution? Note: Note that in this case there is no difference between angular velocity and frequency.
An object with a mass of m=5.10 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.250 m and mass M= 3.00 kg.

A solid cylinder with radius 0.160 mm is mounted on a frictionless, stationary axle that lies along the cylinder axis. The cylinder is initially at rest. Then starting at tt = 0 a constant horizontal force of 5.00 NN is applied tangentially to the surface of the cylinder. You measure the angular displacement θ−θ0θ−θ0 of the cylinder as a function of the time tt since the force was first applied. When you plot θ−θ0θ−θ0 (in radians) as a function of t2t2 (in s2s2), your data lie close to a straight line. If the slope of this line is 16.0 rad/s2rad/s2, what is the moment of inertia of the cylinder for rotation about the axle? Why is the acceleration 32 rad/s^2 in this case?
