A box is placed on a plank. One end of the plank is gradually raised. When the angle of inclination with the horizontal reaches 30, the box starts to slip, and then slides 2.5 m down the plank in 4.5 seconds. Find the Coefficient of static friction, and (b) coefficient of kinetic friction between the box and the plank.

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...
