One end of an ideal spring is fixed to a block of mass m and the other end is free The block is placed over a smooth horizontal floor Initially the spring is unstressed and the block is at rest Now the free end of spring is pulled to right with a constant horizontal velocity of magnitude v For this given spring b system match the statements given in column I with statements in column II 000000 77777 Column I A When the length of spring is maximum B When the length of spring is minimum C When the length of spring is equal to its natural length D When the net force on the block is zero Column II p the speed of block is v q the speed of block may be zero r the speed of block may be 2 v s the kinetic energy of block may be maximum
