Velocity Of Centre Of Mass Of System

Acceleration Of Centre Of Mass Of System

Two block A and B of masses m and 2m respectively are connected by a spring of spring cosntant k. The masses are moving to the right with a uniform velocity v_(0) each, the heavier mass leading the lighter one. The spring is of natural length during this motion. Block B collides head on with a thrid block C of mass 2m . at rest, the collision being completely inelastic. The velocity of centre of mass of system of block A, B, & C is -

Three bodies A , B and C having masses 10kg , 5kg and 15kg respectively are projected from top of a tower with A vertically upward with 10m//s , B with 20m//s 53^(@) above east horizontal and C horizontally southward with 15m//s . Find (a) Velocity of centre of mass of the system. (b) Acceleration of centre of mass of the system.

The velocity of centre of mass of the system remains constant, if the total external force acting on the system is.

As observed in the laboratory system , a 6 MeV proton is incident on a stationary 12 C target. The velocity of centre of mass of the system is (Take mass of proton to be 1 amu)

Two partticles A and B intially at rest move towards each other under a mutual force of attraction. The instant at which velocity of A is 4v and velocity of B is 2v , the velocity of centre of mass of the system at that instant will be
