A box is sitting on a board. One side of the board is raised until the box starts sliding. When it starts sliding the angle of the board from horizontal is 36.869898 degree. The board is then held at that angle. The acceleration of the box down the board is 1.96m/s^2. a) What is the coefficient of static friction between the box and the board? (The model for this problem and the answer) b) What is the coefficient of kinetic...

A box is sitting on a 2 m long board at one end. A worker picks up the board at the end with the box so it makes an angle with the ground of 35o. The coefficient of static friction between the box and the board is 0.5 and the coefficient of kinetic friction is 0.3 . A) Will the box slide down the ramp when it is at 35o? Prove it! B) How long will it take the box...

A uniform board is leaning against a smooth vertical wall. The board is at an angle above the horizontal ground. The coefficient of static friction between the ground and the lower end of the board is 0.380. Find the smallest value for the angle , such that the lower end of the board does not slide along the ground.

A box remains at rest on an incline. The force of gravity acting on the box is directed down and has a magnitude of 10.0 N. The angle the incline makes with the horizontal is 40.0 degrees - this is the maximum angle the incline can have before the box starts to slide. Calculate the magnitude of the normal force acting on the box. Calculate the magnitude of the force of static friction acting on the box. Calculate the value...

A small box of mass m1 is sitting on a board of mass m2 and length L.
A small box of mass m1 is sitting on a board of mass
m2 and length L. The board rests on a frictionless
horizontal surface. The coefficient of static friction between the
board and the box is μs. The coefficient of kinetic
friction between the board and the box is, as usual, less than
μs.Throughout the problem, use g for the magnitude of the acceleration
due to gravity. In the hints, use Ff for the magnitude
of the friction force...

A box of books is initially at rest a distance D = 0.441 m from the end of a wooden board. The coefficient of static friction between the box and the board is μs = 0.331, and the coefficient of kinetic friction is μk = 0.296. The angle of the board is increased slowly, until the box just begins to slide; then the board is held at this angle. Find the speed of the box as it reaches the end...
