The 15.0 kg block to the right is sliding down the inclined plane at a constant velocity.  What is the kinetic coefficient of friction?

A.     0.0282

B.     0.423

C.     0.466

D.     0.906

      

For object sliding at a constant velocity down an inclined plane

Kinetic Coefficient of Friction = Tan A

Kinetic Coefficient of Friction = Tan 25o = 0.466

The Correct Answer is C.
