The 300-series Shinkansen trains consist of 16 aluminum cars with a combined mass of 7.10 X 105 kg. The reduction in mass from the 100- series enables the 300-series trains to reach top speed of 270 km/h. What is the momentum of one of these trains at its top speed? Is the
momentum of a 300-series train greater or less than the momentum of a 100-series train traveling at its top speed?
