Question

The total linear momentum of a system of particles about the centre of mass is

Answer 1

Answer:

Explanation:If the net force acting on an object is zero, its linear momentum is constant (conservation of linear momentum). " The linear momentum of a system of particles is equal to the product of the total mass M of the system and the velocity of the center of mass. "

Answer 2

The centre of mass is:

Explanation:

• On the off chance that the net power following up on an article is zero, its straight force is steady (protection of direct energy).
• " The straight energy of an arrangement of particles is equivalent to the result of the all out mass M of the framework and the speed of the focal point of mass. "
• Thus, we might express that, an arrangement of particles' all out straight force is equivalent to the result of the framework's all out mass and the speed of its Center of mass. dV ⁄ dt is the speed increase of the focal point of mass.
• The energy of a disconnected arrangement of particles is moderated. The powers are inside in nature and summarizes to zero for whole framework.
• As the outside force is zero on framework it's energy stays preserved.
