In figure, block A is released from rest, when spring is at its natural unstretched length. For block B of mass M to leave contact with the ground at some stage, the minimum mass of A must be

In the adjoining diagram the ball A is released from rest when the spring is at its natural length (neither stretched nor compressed) For the block B of mass M to leave contact with the ground at some time, the minimum mass of A must be:

In the arrangement shown in the fig. string, springs and the pulley are mass less. Both the springs have a force constant of k and the mass of block B resting on the table is M. Ball A is released from rest when both the springs are in natural length and just taut. Find the minimum value of mass of A so that block B leaves contact with the table at some stage

In the arrangement shown in the figure, block B of mass M rests on a weighing scale. Ball A is released from a position where spring is in its natural length and the scale shows the correct weight of block B. Find the mass of ball A so that the minimum reading shown by the scale subsequently is half the true weight of B.

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

Block m is released from rest when spring is in its natural length ( assume pulley is ideal and block does not strike on ground during it's motion in vertical plane ) than :

In the figure shown, the system is released from rest with both the springs in unstretched positions. Mass of each block is 1 kg and force constant of each spring is 10 N/m. Maximum speed of the block placed horizontally is:

The system is released from rest with spring intially in its natural length. If mass of the block m = 10 kg. and spring constant k = 100 N//m , then maximum extension in spring is :
