A system consists of two particles at different locations near the origin. Particle 1 has a mass of 7.89 kg and is located on the x-axis at x = –5.0 m while Particle 2 has 9.75 kg mass and is located at y = +8.0 m. What is the center of the mass of the two particles at x – axis?
x = -1.68 mi
x = -2.24 mi
x = 2.18 mi
x = 4.82 mi

A system consists of two particles at different locations near the origin. Particle 1 has a mass of 7.89 kg and is located on the x-axis at x = –5.0 m while Particle 2 has 9.75 kg mass and is located at y= +8.0 m. What is the vector coordinates of the given problem?
r = 4.82 mi – 3.21 mj
r = -1.68 mi – 1.25 mj
r = - 2.24 mi + 4.42 mj
r = 2.18mi + 5.03 mj
