Floor lamps usually have a base with large inertia, while the long body and top have much less inertia. Part A If you want to show off by spinning a floor lamp like a baton, where should you grab the lamp?

When a an object is been rotated its resistance capacity to that rotational force is know as rotational inertia  and this mathematically given as

   Where m is the mass

                r is the rotation radius

For the spinning of the lamp as a baton to work the location of the center of mass of the floor lamp needs to be located

This is more likely to be located closer to base of the lamp as compared to the top, so success of spinning a floor lamp like a baton is highly likely if the lamp is grabbed closer to the base because that is where the position of its center of mass is likely to be.

Explanation:

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
