Problem 4: A coal car of mass m, = 4274 kg is rolling down the tracks at a velocity of v; = 3.9 m/s when a loader drops a load of coal m2 = 5503 kg into the car. Randomized Variables m = 4274 kg m2 = 5503 kg v; = 3.9 m/s Part (a) What is the momentum of the system in (kg m)/s before the coal is added? Numeric : A numeric value is expected and not an expression. P = Part (b) What is the velocity after the coal is added in meters per second? Numeric : A numeric value is expected and not an expression 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 car in kg? Numeric : A numeric value is expected and not an expression. m2' =

Please answer question 4

Problem 4: A coal car of mass mj = 4274 kg is rolling down the tracks at a velocity of v; = 3.9 m/s when a loader drops a load of coal m2 = 5503 kg into the car. Randomized Variables m¡ = 4274 kg m2 = 5503 kg V; = 3.9 m/s Part (a) What is the momentum of the system in (kg-m)/s before the coal is added? Numeric : A numeric value is expected and not an expression. P = Part (b) What is the velocity after the coal is added in meters per second? Numeric : A numeric value is expected and not an expression. 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? Numeric : A numeric value is expected and not an expression. m2' =
