Which train described below would have the greatest momentum?

A. A 9500 kg train car moving at 200 mph
B. An 8000 kg train car moving at 215 mph
C. A 9300 kg train car moving at 190 mph
D. An 8600 kg train car moving at 195 mph

Answer :

Final answer:

To find the train with the greatest momentum, calculate the momentum for each train car using the formula P = mv, where P is momentum, m is mass, and v is velocity. Then, compare the calculated momentum values to determine which train has the greatest momentum.

Explanation:

In order to determine the train with the greatest momentum, we need to calculate the momentum of each train car. Momentum is given by the formula P = mv, where P is momentum, m is mass, and v is velocity.

Let's calculate the momentum for each train car:

  • Train car A: PA = (9500 kg)(200 mph)
  • Train car B: PB = (8000 kg)(215 mph)
  • Train car C: PC = (9300 kg)(190 mph)
  • Train car D: PD = (8600 kg)(195 mph)

After calculating the momentum for each train car, we can compare the values to determine which train has the greatest momentum. The train car with the highest calculated momentum will have the greatest momentum.
