13) A short commutator train consists of a locomotive and two cars. The mass of the locomotive is 6000kg and that of each car is 2000kg. The train pulls away from a station with an acceleration of 0.5ms -2. Determine the horizontal pulling force that the locomotive wheels exert on the track, the tension between the couplings joining the two cars and the tension between the couplings joining the two cars.

A 63.0 kgkg parachutist falling vertically at a speed of 6.50 m/sm/s hits the ground, which brings him to a complete stop in a distance of 0.87 mm (roughly half of his height). 1) Assuming constant acceleration after his feet first touch the ground, what is the average force exerted on the parachutist by the ground? Express your answer with the appropriate units.

Two constant forces of magnitudes F1 and F2, act on a particle of mass 5.00 [kg] which is at rest at the origin. The force F1 points at 14.5° west of north, while the force F2, points at 58.3° west of south. Due to the two forces, the particle accelerates and is later located at 32.4 [m], 17.0° north of west with speed 12.2 [m/s]. What is F1?
