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 friction between the box and the board? (The model for this problem and the answer)

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 chimpanzee named Allison pushes a box. She loads the box full of her toys until it has a mass of 8 kg. The coefficient of kinetic friction between the box and the floor is mu k = 0.4. The box is initially in motion, and moving at a velocity of 1.2 m/s to the right. a) If Allison pushes horizontally to the right with a force of 60N, what is the acceleration of the box? Is the box speeding...

Question 8 A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank. She places the box on the plank and gradually raises one end of the plank. When the angle of inclination with the horizontal reaches 20°, the box starts to slip, and it then slides 2.2 m down the plank in 1.9 s at constant acceleration. What are (a) the coefficient of static friction and (b) the coefficient of kinetic...

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...
