A person is trying to udge whether a picture mass = 1.09 kg) is properly positioned by temporarily pressing it against a wall. The pressing force is perpendicular to the wall. The coefficient of static friction between the picture and the wall is 0.680. What is the minimum amount o pressing force that must be used?
A horizontal force F of module 12 N is exerted on a block, whose weight is...
A horizontal force F of module 12 N is exerted on a block, whose
weight is 5 N, to try to hold it against a vertical wall. It is
considered that the coefficient of static friction (μs)
between the wall and the block is 0.60 while the coefficient of
dynamic friction (μc) is 0.40. Initially, the block is
rest. Under these conditions, will the block move? Support your
answer with a calculation.

In the figure, a block weighing 22.0 N is held at rest against a vertical wall by a horizontal force F of magnitude 60 N. The coefficient of static friction between the wall and the block is 0.55, and the coefficient of kinetic friction between them is 0.38. In six experiments, a second force is applied to the block and directed parallel to the wall with these magnitudes and directions: 33 N, up, 13 N, up, 47 N, up, 61...

In the experiment to measure the coefficient of kinetic friction by sliding a block down on inclined plane, it is required that the block move at constant velocity. Why is this requirement necessary? 5. Frictional forces on a block on an inclined plane are directed down the plane (TRUE/FALSE). 9. How does the coefficient of kinetic friction depend on the constant speed of a moving object?
