A solid cube of side 2a and mass M is sliding on a frictionless surface with uniform velocity → v as shown in Figure . It hits a small obstacle at the end of the table that causes the cube to tilt as shown in Figure P11.50b. Find the minimum value of the magnitude of → v such that the cube tips over and falls off the table. Note: The cube undergoes an inelastic collision at the edge.

Because windmill blades (vanes) rotate about a central axis, one of the most important physical properties of a windmill is its moment of inertia. Given is a picture of a typical windmill, where the Center of mass geometry and center of mass of one of the vanes is illustrated. The mass of each vane is 207 kg. The distance from the center of mass of the vane to axis B is k, = 2.45 m. The distance from the center of mass of the vane to the center of the windmill hub is k, = 3.80 m. If the moment of inertia of a vane about axis A is 241 kg-m2 and about axis B is 5860 kg-m2, calculate the moment of inertia Itotal of the entire assembly about the axis that passes through the windmill's hub and is perpendicular to the screen.
