(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A loaded coal car with a mass of 120 metric tons traveling at 2 m/s collides and couples with an empty, stationary coal car with a mass of 8 metric tons. (1 metric ton = 103 kg)

(c) What is the speed of the center of mass of the system of two cars throughout the process?

2. Relevant equations

I am not sure of any relevant equations for part c but I know that M1r1=M2r2 deals with center of mass systems.

3. The attempt at a solution

I already solved parts a and b which are about final speed of two cars, and change in kinetic energy respectively.

Thanks for the help
