Kinetic coefficient of friction among the block and plank

Reference no: EM13680791

A block is at rest on a plank whose angle can be varied. The angle is gradually increased from 0 deg. At 31.3°, the block starts to slide down the incline, traveling 2.80 m down the incline in 2.40 s.

1. Compute the coefficient of static friction between the block and the plank.

2. Calculate the kinetic coefficient of friction among the block and the plank.
