A uniform rod of length L and mass M has been placed on a rough horizontal surface. The force F applied on the rod is such that the rod is such that the rod is just in the state of rest. If the coefficient of friction varies according to the relation μ=KX, where K is a positive constant. Suppose friction is present only from X=0 to X=L. If the rod moves in the direction of application of force then the total heat generated in the time in which the rod crosses this region, is equal to

A wooden block weighing 80 N rests on a rough horizontal plane, the coefficient of friction between the two being µ=0.4. If a bullet weighing 0.4 N is fired horizontally in to the block with muzzle velocity v= 500 m/s, how far will the block be displaced from its initial position? Assume that the bullet remains inside the block.

JEE main - Physics
Two block A and B each of mass m are connected by a massless spring of natural length L and spring constant k. The blocks are initially resting on a smooth horizontal floor with the spring at its natural length as shown in fig. A third identical block C, also of mass m, moving on the floor with a speed v along the line joining A and B, and collides elastically with A. Then
