A block A of mass `2 kg` is moving to right with a speed of 5 m/s on a horizontal smooth surface. Another block B of mass 2 kg, with a mass less spring of force constant `K =200` N/m attached to it, is moving to left on the same surface with a speed of 3 m/s. Block A collides with the spring attached to B. Calculate
(a) the final velocity of the block A.
(b) the minimum kinetic energy of the system of two blocks during subsequent motion.
(c) Repeat part (b) if there is no spring and the two blocks collide head on. Assume that the blocks are made of perfectly elastic material

Another block B of mass 3kg a massless spring of spring constant 222N//m attached to it, is moving to the left on the same surface and with a speed 2m//s . Let us take the direction to the right as the positive X- direction. At some instant, block A collides with the spring attached to block B . At some other instant , the spring has maximum compression and then, finally, blocks move with their final velocities. Assuming that (i) the spring force is conservative and so there is no conversion of kinetic energy to internal energy and (ii) , no sound is made when block A hits the spring, answer the following questions. When the blocks are yet to attain their final velocities, in this situation at any instant when block A is moving with a velocity 4 hat(i) m//s , velocity of block B will then be :
