A freight train consists of an engine and several identical cars on a straight, level track. Which of the following statements are true? A. If the train is moving at constant speed, the engine must be pulling with a force greater than the train's weight. B. If the train is moving at constant speed, the engine's pull on the first car must exceed that car's backward pull on the engine. C. If the train is moving at constant speed, the engine's pull must be equal to the force of friction. D. If the train is coasting, its inertia makes it slow down and eventually stop

4. Billy Bob Joe is trying to save his crates full of bananas that are in danger of falling over a cliff. He pulls on one of the crates with a rope, applying a force P as shown. He is quite strong, so he is able to pull the crates to safety, so that the whole system is accelerating to safety. a. Write the equation of motion for every object in this system. Your final equations should only have P, m₁, M², M³, M4, g, T1, T2, T3, µk, and 0 in them. Box each equation. b. Solve for the acceleration of the crates in terms of only P, M₁, M2, M3, M4, g, μk, and 0. 3 3 3 4 T 2 T 3 m 2 T 1 μ k m 1
