Strenuous physical exercise may cause fatigue due to accumulation of CO_2 , in the blood

An object of mass 3 kg at rest in space suddenly explodes into three parts of the same mass. The momenta of the two parts are 4hati and 2hatj respectively. Then the energy released in the explosion is

A point particle of mass m, moves long the uniformly rough track PQR as shown in figure. The coefficient of friction, between the particle and the rough track equals mu . 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 value of the coefficient of friction mu and the distance x (=QR) , are, respectively close to:
