Albert presses a book against a wall with his hand. As Albert gets tired, he exerts less force, but the book remains in the same spot on the wall. Classify each force on the book as increasing, decreasing, or not changing in magnitude when Albert reduces the force he is applying to the book. Not every classification must be used. Is each one of the following increasing, decreasing or not changing: 1) weight of the book 2) maximum static frictional force of the wall on the book 3) NORMAL FORCE OF WALL ON THE BOOK 4)frictional force of wall on the book

Inclined Planes A crate is at rest on an inclined plane. As the slope increases the crate remains at rest until the incline reaches an angle of 32.7° from the horizontal. At this angle the crate begins to slide down the ramp. A) What is the coefficient of static friction between the crate and the surface of the ramp? B) If the coefficient of kinetic friction between the surface of the ramp and the crate is 0.33, what would be the acceleration of the moving crate at this angle?
