Two blocks P and Q of masses 0.3 kg and 0.4 kg respectively are stuck to each other by some weak glue as shown in the figure. They hand together at the end of a spring with a spring constant `"k = 200 N m"^(-1)`. The block Q suddenly falls free due to failure of glue, then find the maximum kinetic energy of the block P during subsequent motion (in mJ).

Two blocks are connected to the two free ends of a spring of spring constant K . Both the blocks are moved apart to extend the psring beyond its natural length and then released . In subsequent motion

Two rectangular blocks A and B of masses 2 kg and 3 gk respectively are connected by a spring of spring constant 10.8Nm^(-1) and are placed on a frictionless horizontal surface.

Two block A and B of masses m_(1) = 3kg and m_(2) = 6kg respectively are connected with each other by a spring of force constant k = 200 N//m as shown in figure. Blocks are pulled away from each other by x_(0) = 3cm and then released. When spring is in its natural length and block are moving towards each other, another block C of mass m = 3kg moving with velocity v_(0) = 0.4m//s (towards right) collides with A and gets stuck to it.
