Answer 2

Answer:

15552 N

Explanation:

Mass of the engine = 8000 kg

Number of wagons = 5

Mass of the wagons = 2000 kg

Total mass of the train (m) = Mass of the engine + (Mass of the wagons + Number of wagons)

m = 8000 + (5 × 2000)

m = 18000 kg

Acceleration of the train (a) = 35000/18000

                                               = 1.944m/s2

Force of wagon 1 on wagon 2 = 4 × mass of wagon × a

                                                       = 4 × 2000 × 1.944

                                                       = 15552 N
