1 2500kg railroad car moving with a speed of 3 m/s is linked with a 3500 kg railroad car moving away from the first car with a speed by 1 m/s. Both are moving along a straight track. Find the speed of the two cars just after they link up.
When you drop two marbles at once, why doesn’t only one marble come off the end twice as fast? How would I put this into equation?
