Question:
1. If the acceleration of gravity is not constant over an object, is it the center of mass or the center of gravity that is the pivot point when the object is balanced?
2. A uniform box of mass 8 kg that is twice as tall as it is wide rests on the floor of a truck. What is the maximum coefficient of static friction between the box and floor so that the box will slide toward the rear of the truck rather than tip when the truck accelerates with acceleration a = 0.6g on a level road?

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
