In this Physics video in Hindi for class 11 we gave solution of a numerical problem on FRICTION AND ENERGY from IIT JEE Mains 2016 previous years’ question. Lecture on this question is related to drop in potential energy and energy dissipation by frictional force.

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 μ. 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. The values of the coefficient of friction μ and the distance x (= QR), are, respectively close to:
