A block slides from rest a distance d=5.0m down a 30° frictionless incline and then a distance d2 along a rough horizontal track before it stops (see figure blow). The coefficient of kinetic friction between the block and horizontal track is 4x =0.45. What is the distance d»?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
