A block is at rest on a plank whose angle can be varied. The angle is gradually increased from 0 deg. At 26.1°, the block starts to slide down the incline, traveling 3.40 m down the incline in 2.10 s. Calculate the coefficient of static friction between the block and the plank. Motion of a block If static friction acts on the block, does it move? What is its acceleration in this case? Calculate the kinetic coefficent of friction between the block and the plank.
