A point particle of mass m, moves along the uniformly rough track PQR as shown in the figure.
The coefficient of friction, between the particle and the rough track equals . The particle is
released, from rest, from the point P and it comes to rest at a point R. The energies, lost by the
ball, over the parts, PQ and QR, of the track, are equal to each other, and no energy is lost when
particle changes direction from PQ to QR.
