Center of mass

Classical Mechanics Level 2

At an instant, a 2 kg 2 \text{ kg} particle has a velocity of 4 m/s 4 \text{ m/s} in + x +x direction and a 3 kg 3 \text{ kg} particle has a velocity of 5 m/s 5 \text{ m/s} in + y +y direction. What is the speed of the center of mass of the two-particle system?

7.0 m/s 7.0 \text{ m/s} 3.4 m/s 3.4 \text{ m/s} 2.2 m/s 2.2 \text{ m/s} 6.8 m/s 6.8 \text{ m/s}

use the formula sum(mass of the system*velocity of system)/sum(mass of system).
