Question

derive the expressions of linear momentum of system of particles​

Answer 1

" 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. " This expression shows that if the net external force acting on a system of particles is zero (Fext = 0 N), the linear momentum of the system is conserved

Answer 2

Answer:

Calculate the angle between the two vectors given by a=3i+3j+3k and b=2i+1j+3k
