Two blocks A and B of mass m and 2m respectively are connected by a massless spring of spring constant K This system lies over a smooth horizontal surface At t 0 the block A has velocity u towards right as shown while the speed of block B is zero and the length of spring is equal to its natural length at that instant In each situation of list 1 certain statements are given and corresponding results are given in list II Match the statements in list l corresponding results in list II F mg List I P The velocity of block A Q The veloicty of block B R S The kinetic energy of system of two blocks The potential energy of spring P 20 2R 1S 3 CP 30 1 R 1S 2 P 30 1R 3S 4 P 20 28 18 4 List ll 1 Can never be zero 2 3 4 may be zero at certain instants of time B 2m is minimum at maximum compression of spring is maximum at maximum extension of spring mm m smooth horizontal surface U 4
