Two particles and have mass and respectively. They are projected along a vertical line with velocity and when separation between them was was projected vertically up while was projected vertically down. Calculate the maximum height attained (in ) by the centre of mass of the system of two particles, measured from the initial position of Assume that the particles do not collide and that the ground is far below their point of projection




Important Questions on System of Particles and Centre of Mass
Two blocks of masses and are connected to a spring of force constant The spring is compressed by 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 perpendicular to the spring. The string snaps while moving. The speed (in ) of the block of mass when the spring regains its natural length is

Three identical particles are placed on a horizontal smooth table, connected with strings as shown. The particle is imparted a velocity in horizontal direction perpendicular to the line The speed (in ) of particle when it is about to collide with
