HW 4.1: Accelerating Systems (pg. 2 of 2)Q2Train Example: A train engine pulls a train with three cars. Each car has the mass shown. Suppose that the cars are connected by ropeswith the tensions indicated in the diagram. The engine accelerates at a rate of 2 m/s². Assume that the cars travel on frictionless bearings.3000 kg2000 kg1000 kg(a) On the dots below, draw free-body diagrams showing the forces acting on each of the three train cars. For each diagram, write anequation that relates the forces in the diagram to acceleration.Forces on the 3000 kg carForces on the 2000 kg carForces on the 1000 kg car10-9(b) On the squares below, draw external force diagrams showing only the external forces acting on each of the systems indicated. Pleaseomit forces that balance. For each diagram, write an equation that relates the forces in the diagram to acceleration.Forces on the 2000-1000 systemForces on 3000-2000-1000 systemForces on the 3000-2000 system(c) Use the equations you wrote above to find each of the three tensions T1, T2, and T3.(d) Without referencing any math or any numbers, explain why Ti is the greatest tension and T3 is the weakest tension, even though T3 isconnected to the greatest mass.

(Newton's laws and their applications) A block with mass m1 slides down an inclined plane whose angle is 22 °, the coefficient of kinetic friction between the block and the plane is 0,250. The block is attached to an ideal rope that passes through two ideal pulleys until it is attached to a fixed support, as shown in figure 3. A rope leaves the axis of the movable pulley up to a block of mass m2 3 m2 m1 Figure 3. Diagram of exercise 3 A. Discuss what difference the exercise will make if one more pulley is placed on the ceiling that makes the rope connect to the rod of the movable pulley.
