Question

show that the product of total mass of a system of particles and the acceleration of its centre of mass is a vector sum of all forces acting on the system of particles​

Answer 1

Answer:

The centre of mass (CoM) is the point relative to the system of particles in an object. This is that point of the system of particles that embarks the average position of the system in relation to the mass of the object. At the centre of mass, the weighted mass gives a sum equal to zero. It is the point where any uniform force applied on the object acts.
