A Norman window has the shape of a rectangle surmounted by a semicircle
A Norman window has the shape of a rectangle surmounted by a semicircle. (Thus the diameter of the semicircle is equal to the width of the rectangle.) If the perimeter of the window is 24 ft, find the value of x so that the greatest possible amount of light is admitted.

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.

To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the...
