Whenever you face a problem involving forces, always start with a free-body diagram.
Learning Goal: To gain practice drawing free-body diagramsWhenever you face a problem involving forces, always start with a free-body diagram.To draw a free-body diagram use the following steps:Isolate the object of interest. It is customary to represent the object of interest as a point in your diagram.Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that do...

Part 3:
Let system A now contain just the lower brick on the
stack of two bricks. Call the top brick system C. Now we have three
systems, one for each brick. The hand is pushing horizontally with
a constant speed. In this situation the coefficient of friction
between the bricks and table is less than that in question 1 (where
the friction was not negligible and the coefficient of friction was
not given).
A. Compare the magnitude of the...
