A railroad Diesel engine weighs 4 times as much as a freight car. If the Diesel engine coasts at a 5km/hr into a freight car that is at rest, how fast do the two coast after they?do they have different impulse? – Quora

A railroad diesel engine weighs four times as much as a freightcar. If the diesel engine coasts at 5km/h into a freightcar that is initially at rest, how fast do the two coast after they couple together?

What is the difference between a freight car and a diesel engine?

A railroad Diesel engine weighs 4 times as much as a freight car. If the Diesel engine coasts at a 5km/hr into a freight car that is at rest, how fast do the two coast after they?do they have different impulse? – Quora Something went wrong.

What is the collision between a diesel engine and a freight car?

This exercise involves an inelastic collision between a railroad diesel engine moving at 5 km/h and a stationary freight car. The diesel engine weighs four times as much as the freight car: in the work, the mass of the freight car is ”M” and the mass of the diesel engine is ”4M”

How heavy is a train?

How heavy a train is relates to mainly how many cars the locomotive is pulling. A train car weighs between 30-80 tons. Passenger cars like sleepers & coaches are heavier than an empty freight car. A train consists of locomotives and cars. In some situations there can be up to 6-8 locomotives for one train, depending on the load and number of cars.

How much do locomotives weigh?

Of that weight 848 tons (1,869,519 lbs) would be the total weight of the locomotives and 18,340 tons (40,432,778 lbs) the total weight of the loaded grain hopper cars. The average locomotive weights around 210-220 tons (465,000 – 480,000 lbs). Of course there are many types/models each with different weight, so let’s look at some examples.

A railroad diesel engine weighs four times as much as a freight car. The diesel engine coasts at 4.8 km/h into a freight car that is initially at rest. Part A Use conservation of momentum to find a speed at what the engine + car coast after they couple together.

Answer (1 of 6): Initially all of the momentum is in the engine and is numerically equal to the product of the mass times the velocity. Let’s let m be the mass of the flat car and 4m be the mass of the engine. The initial momentum equals (5 km/h)(4m). Assuming an elastic collision, the final mome…

How much fuel does a diesel engine use per hour?

As a pretty good rule of thumb, a modern Diesel engine uses about 0.31 pounds of fuel per hour per horsepower. A large 6000 HP mainline locomotive would use ~1860 pounds of fuel per hour if operated at full throttle. More typically, the engine would be run at ~80% of full power, or 1488 pounds/hour (roughly 250 gallons/hour).

How do car diesels work?

Many car diesels are based on existing petrol engine designs, but with the major components strengthened to cope with the higher pressures involved. Fuel is supplied by an injection pump and metering unit, which are usually mounted on the side of the engine block.

Since the masses are the same, the speed of car B is equal to the initial speed of car A. If the equally massive cars of the previous question stick together after colliding inelastically, how does their speed after the collision compare with the initial speed of car A? Again, the momentum of car A is transferred, this time to both cars.

How does the speed after the collision compare with the initial speed?

The speed of car B is equal to the initial speed of A. If the equally massive cars of the preceding question stick together after colliding inelastically, how does their speed after the collision compare with the initial speed of car A? Their speed is half the initial speed of car A.

Is the speed of car B equal to the initial speed?

The speed of car B is equal to the initial speed of A. If the equally massive cars of the preceding question stick together after colliding inelastically, how does their speed after the collision compare with the initial speed of car A?

What happens when a railway car rolls at a certain speed?

Railroad car A rolls at a certain speed and makes a perfectly elastic collision with car B of the same mass. After the collision, car A is observed to be at rest.

The truck at rest has no speed, hence no momentum. So the moving automobile has greater momentum. How can a supertanker have a huge momentum when it moves relatively slowly? It has a huge momentum because its mass is so huge. Why is it incorrect to say that impulse equals momentum? Impulse equals a change in momentum, not momentum itself.

Does a truck have more momentum than a car?

And since you mentioned that the car and the truck has the same velocity, we can still assume that a truck has more mass, than the car. Thus the truck has more momentum. Momentum is defined as mass multiplied by velocity. So if both vehicles have the same velocity then the one with the higher mass has the higher momentum.

Do cars with the same mass have the same momentum?

So a car and a truck that is a thousand pounds heavier may have the SAME momentum if the car is traveling faster than the truck. That said, there are some very heavy cars. For example, a Tesla Model S sedan, with its battery pack, has almost the same mass as a Ford F150 truck. So you can do the math.

Are a truck and a car moving with the same velocity?

A truck and a car are moving with same velocity. If breaks are applied at the same time, which would cover more distance till they are at rest?

Does a skateboard have more momentum than a truck?

Momentum = mass x velocity, so, by definition, the moving skateboard has some momentum, and that is more momentum than the stationary truck that has a momentum of zero. Momentum is related to kinetic energy, and the truck has no kinetic energy.
