A train locomotive pulls a train with a mass of 1.30 ✕ 107 kg on level rails. The locomotive exerts a constant force of 7.40 ✕ 105 N on the train. How much time does it take to increase the speed of the train from rest to 64.0 km/h? (Ignore any resistance force from the rails on the wheels of the train. Enter your answer in minutes.) ______min

Trains are connected by couplers, which are under tension as the locomotive pulls the train. Imagine you are on a train speeding up with a constant acceleration. As you move through the train from the locomotive to the last car, measuring the tension in each set of couplers, does the tension increase, decrease, or stay the same? When the engineer applies the brakes, the couplers are under compression. How does this compression force vary from the locomotive to the last...

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...

A train consists of a 50 Mg engine and three cars, each having a mass of 30 Mg. If it takes 80 s for the train to increase its speed uniformly to 43 km/h, starting from rest, determine the force T developed at the coupling between the engine E and the first car A. The wheels of the engine provide a resultant friction tractive force F which gives the train forward motion, whereas the car wheels roll freely. Also, determine...
