Front

A 9300 kg railroad car traveling at a velocity of 5 m/s strikes a second boxcar that weighs 5000 kg at rest. The railroad car is brought to a sudden stop while the boxcar moves away from the collision. At what speed will the second boxcar move?

Back

9.3 m/s

Front

What happens to the momentum of a toy car if the mass is doubled and the velocity decreases by 1/2?

Back

Stays the same
