A coal car of mass m₁ = 3557 kg is rolling down the tracks at a velocity of v; = 3.7 m/s when a loader drops a load of coal m₂ = 5376 kg into the car. Randomized Variables m₁ = 3557 kg m₂ = 5376 kg v₁ = 3.7 m/s a) What is the momentum of the system in (kg m)/s before the coal is added? b) What is the velocity after the coal is added in meters per second?
