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

Car A with mass 2400 kg is moving along a straight stretch of road at 45 miles per hour. Car B with mass 1100kg follows with speed 65 miles per hour. How fast is the center of mass of the 2 cars moving?

2. Relevant equations

Xcm=(M1X1+...+MnXn)/ (M1+...+Mn)

3. The attempt at a solution

hmm i did

(2400kg x 45mph +1100kg x 65 mph)/ (1100kg+2400kg)= 51.3 mph

But that seems a bit too easy..
