A block is at rest on a plank whose angle can be varied. The angle is gradually increased from 0 deg. At 27.1°, the block starts to slide down the incline, traveling 2.80 m down the incline in 1.70 s. Calculate the coefficient of static friction between the block and the plank.

Calculate the kinetic coefficent of friction between the block and the plank.
