What is the Mass of Water Collected?
A 5000 kg open train car is rolling on frictionless rails at 22.0 m/s when it starts pouring rain. A few minutes later, the car’s speed is 20.0m/s. What mass of water has collected in the car? Known Variables: Mass of train (m1) = 5000 kg v1 = 22 m/s v2 = 20 m/s Conservation of momentum: Pi – Pf = 0…
