Two particles of masses m and 2m moving in opposite directions collide elastically with velocity 2v and v , respectiely. Find their velocities after collision.

Two objects A and B are moving along the directions as shown in (Fig. 5.77). Find the magnitude and direction of the relative velocity of B w.r.t. A . ,

Two plates identical in size, one of black and rough surface (B_1) and the other smooth and polished (A_2) are interconnected by a thin horizontal pipe with a mercury pellet at the centre. Two more plates A_1 (identical to A_2 ) and B_2 (identical B_1 ) are heated to the same temperature and placed closed to the plates B_1 , and A_2 shown in Fig. The mercury pellet
