11.2 The baggage truck A has a mass of 800 kg and is used to pull two cars, each with a mass of 300 kg. If the tractive force F on the truck is F = 480 N, determine the initial acceleration of the truck. What is the acceleration of the truck if the coupling at C suddenly fails? The car wheels are free to roll; neglect the mass of the wheels.

Ans: a = 0.343 m/s2, a = 0.436 m/s2

  1. acceleration= force/total mass

    total mass is 2000kg, if my math is correct.

    I don't know where C is, but just subtract the mass following C.
