In the Figure an Airport Luggage Carrying Train with a Tractor

Multiple Choice

In the figure an airport luggage carrying train with a tractor T is pulling three luggage carts M₁, M₂, and M₃, with constant velocity of 4.5 m/s. Unfortunately, the wheels on the carts have locked up and are sliding rather than rolling. If T = 300.0 kg, M₁ = 200.0 kg, M₂ = 100.0 kg, and M₃ = 100.0 kg, and the coefficient of kinetic friction for each is 0.4000, what is the force in the connection between the tractor T and cart M₁? Use g = 9.8 m/s.
