Homework Help: Physics

Posted by James on Tuesday, June 12, 2012 at 12:14pm.

A system consists of two particles. Particle 1 with mass 2.0 kg is located at (2.0 m, 6.0 m) and has a velocity of (2.1 m/s, 4.1 m/s). Particle 2 with mass 4.5 kg is located at (4.0 m, 1.0 m) and has a velocity of (4.6 m/s, 4.6 m/s). Determine the position and the velocity of the center of mass of the system.

I know the answers are:

Position: 3.38x + 2.54y
Velocity: 3.83x + 4.45y

How does one arrive at these answers?
