Two blocks of masses m = 2 kg and m= 8 kg are connected to a spring of force constant K = 1 k N/m. The spring is compressed by 20 cm and the two blocks are held in this position by a string. The system is placed on a horizontal smooth surface and given a velocity u=3 m/s perpendicular to the spring. The string snaps while moving. Find the speed of the block of mass m when the spring regains its natural length.

Two particles P and Q have mass 1 kg and 2 kg respectively. They are projected along a vertical line with velocity up = 20 m/s and uQ = 5 m/s when separation between them was 60 m. P was projected vertically up while Q was projected vertically down. Calculate the maximum height attained by the centre of mass of the system of two particles, measured from the initial position of P. Assume that the particles do not collide and that the ground is far below their point of projection [g= 10 m/s^2]
