A locomotive is pulling 19 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at .22 m/s^2 on a level track, what is the tension in the coupling between the third and fourth cars? (The car nearest the locomotive is counted as the first car, and friction is negligible.)
6. A locomotive is pulling two freight cars with an acceleration of 0.520 m/s2. The mass of the first car is 51500 kg , while that of the second car is 18400 kg . Find the tension (T) in the coupling mechanisn between the engine and the first car, and the tension (T) in the coupling mechanisn between the first car and the second car.
Locomotive A pulls the train B and C. Between locomotive A and train B, there is a coupler and the coupler’s tension is ?1, also between train B and train C there is a coupler and its tension is ?2. There are frictions between locomotive A and trains B and C and the rail beneath them, and the friction coefficient is ?. Meanwhile, locomotive A generates a traction ? on its wheel. Train B and train C has equal mass...
#8 Mechanical Equilibrium: suspended blocks A 10.4 kg mass is suspended from the ceiling with a cable of negligible mass. A 12.5 kg mass is attached (and suspended below) the 10.4 kg mass with a cable, also of negligible mass. What are the tensions, respectively, connecting the 10.4 kg mass to the ceiling (cable 1) and the cable connecting the 12.5 kg mass to the 10.4 kg mass (cable 2) O A. cable 1: 102 N; cable 2: 123 N...
A train consists of a 4300-kg locomotive pulling two loaded boxcars. The first boxcar has a mass of 12,700 kg and the second 16,300 kg. Presume that the boxcar wheels roll without friction and ignore aerodynamics. The acceleration of the train is 0.559 m/s2 (a) With what force, in Newtons, do the boxcars pull on each other? (b) With what force (N) do the locomotive and first boxcar pull on each other? (c) With what force (N) must the tracks...
A locomotive of mass m= 1.134 X 105 kg uses 37.8 kW of power to accelerate at a constant rate for 15.0 s. a) The locomotive has an initial velocity of 0.500 m/s east. Calculate the locomotive’s speed after 15.0 s. After 15.0 s, the locomotive travels east at a constant speed and then collides and couples with a train of four cars. Each of the cars has half the mass of the locomotive. Before the collision, the train was...

Sketch the free-body diagram of a baseball (a) at the moment it is hit by the bat. and again (b) after it has left the bat and is flying toward the outfield. Ignore air resistance. Arlene is to walk across a "high wire" strung horizontally between two buildings 10.0 m apart. The sag in the rope when she is at the midpoint is 10.0". as shown in Fig. 4-47. If her mass is 50.0 kg. what is...
A train consists of a caboose (mass = 1000 kg), a car (mass = 2000 kg), and an engine car (mass = 2000 kg). See the diagram below. If the train has an acceleration of 5 m/s^2, the tension force in the coupling between the middle car and the engine is 25.000 N 20.000 N 15.000 N 10.000 N
A 2400-kg airplane pulls two gliders, the first of mass 330 kg and the second of mass 280 kg, down the runway with an acceleration of 1.3 m/s2 (Figure 1). Neglect the mass of the two ropes and any frictional forces. Part A: Determine the magnitude of horizontal thrust of the plane's propeller. Part B: Determine the magnitude of the tension force in the first rope. Part C: Determine the magnitude of the tension force in the second rope. Part...

Two crates, one with mass 4.00 kg and the other with mass 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope (Figure 1). A woman wearing golf shoes (so she can get traction on the ice) pulls horizontally on the 6.00 kg crate with a force F that gives the crate an acceleration of 290 m/s 6.00 kg よ 00 kg T he woman is pulling two c rope that connects...
