Momentum calculations

Total momentum before = 60,000 + 0 = 60,000 kg m/s.

  1. Because momentum is conserved, total momentum afterwards = 60,000 kg m/s.
  2. Total mass = mass of carriage A + mass of carriage B = 12,000 + 8,000 = 20,000 kg.
  3. p = m × v, but we can rearrange this equation so that v = p ÷ m.
