Question

A track has inclined surfaces AB and AC, each of length 3 cm and angle of inclination of 30° with the horizontal and a central point a horizontal point of length 4 cm as shown. A block of mass 0.2kg slides from rest from point A. The inclined surfaces are frictionless. If the coefficient of friction between the block and the horizontal flat surface is 0.2, at what distance from C will the block finally come to rest (in 10^-2 m)
