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.
