A 20000 kg railroad car is rolling at 6 m per s when a 8000 kg load of gravel is suddenly dropped in What is the car's speed just after the gravel is loaded?
The initial momentum of the railroad car is 120,000 kgm/s (20,000 kg * 6 m/s). When the 8000 kg load of gravel is dropped in, the total momentum is conserved. Therefore, the final speed of the railroad car can be calculated by dividing the total momentum (120,000 kgm/s) by the new total mass (28,000 kg). This gives a final speed of 4.29 m/s.
