Preview A train of mass 2.450 kg pushes a carriage of mass 1,030 kg along a straight horizontal track The engine is connected to the carriage by a coupling rod which is parallel to the direction of motion of the train The horizontal resistances of motion of the train and the camage have magnitudes R N and 570 N respectively The engine of the train produces a constant horizontal driving force of magnitude 8.200 N that causes the train and carnage to accelerate at 1 8 ms a) Calculate the resistance to motion R acting on the train (3 marks) Number Units b) Find the magnitude of the compression in the coupling (2 marks) Number Units The train must stop at the next station so the driver reduces the force produced by the engine to zero and applies the brakes. The brakes produce a force on the train of magnitude 1,525 N causing the engine and carriage to decelerate c) Given that the resistances to motion are unchanged (from parts a) and b) above), find the magnitude of the tension in the coupling (5 marks) HINT Find the acceleration of the system first Number Units
