Answer 1

Answer:

hope it helps

Explanation:

The linear momentum of a body is defined as the product of its mass and velocity and is give by: p⃗ = mv⃗

If F is the net force acting on the object then,

∑F⃗ = ma⃗ = m dv⃗ /dt = dp⃗ /dt

Or, the rate of change of the linear momentum is equal to the amount of force acting on the body.

Let us suppose that p is the total linear momentum of a system of particles which is given as the vector sum of the momenta of the individual particles.Then,

p⃗ = ∑ni pi→

or, it can be rewritten as:

p⃗ = ∑nimivi→ = Mvcom

Hence,

We can say that the total linear momentum of a system of particles is equal to the product of mass of the whole system and the velocity of the centre of mass.
