At one instant, the center of mass of a system of two particles is located on the -axis at = 2.0m and has a velocity of (5.0m/s ) . One of the particles is at the origin. The other particle has a mass of 0.10kg and is at rest on the -axis at = 8.0m .
A) What is the mass of the particle at the origin?
B)Calculate the total momentum of this system.
C)What is the velocity of the particle at the origin?
