Homework Statement
Consider a system consisting of three particles:
m1=5kg, v1=
m2=7kg, v2=
m3=1kg, v3=
What is the total momentum of this system?
What is the velocity of the center of mass of this system?[/B]
Homework Equations
p=m*v
The Attempt at a Solution
I tried (m1+m2)(v1+v2) + (m2+m3)(v2+v3)
and (m1+m2+m3)(v1+v2+v3), neither were correct...
