A coal car m1 = 3411 kg is rolling down the tracks at a velocity of vi = 2.6 m/s when a loader drops a load of coal m2 = 5411 kg into the car.
Part (a) What is the momentum of the system in kg m/s before the coal is added?
Part (b) What is the velocity after the coal is added in meters per second?
Part (c) If you measured the final velocity of the car to be 1 m/s and the initial mass of the car remains the same, how much coal was added to the car in kg?
