Determine the co-ordinates of centre of mass of a system of n particles.

Define centre of mass of a system of particles.

In the co-ordinate valency

Define centre of mass.

Separation of mmotion of a systme of particles into motion of the centre of mass and motion about the centre of mass Show vec L = L = vec L + vecM R xx vecV where vec L = Sigma vecr_i xx vecp_i is the angular momentum of the system about the centre of mass with velocities taken relative to the centre of mass. Remember vecr_i = vecr_i - vecR , rest f the notation is the standard notation used in the chapter. Note vecL and vecMR xx vecV can be said to be angular moemnta respectively about and of the centre of mass of the system of particles.

Is centre of mass a reality?

Does the centre of mass of a system of two particles lie on the line joining the two particles?

Draw the graphs of the 5x-y=5 and 3x-y=3. Determine the co-ordinates of the vertices of the triangle formed by these lines and the y axis.
