How much momentum does a freight train have?

Trains on average weigh between 8,000 to 10,000 tons and travel approximately 40 mph or 17.9 m/s. The average train would have a momentum between 143,200? 179,000 ton*m/s as it travels.

Which has more momentum a large truck moving at 30miles per hour or a small truck moving at 30 miles per hour?

mass times its velocity. Which has more momentum, a large truck moving at 30 miles per hour or a small truck moving at 30 miles per hour? twice as much momentum.

Which has more momentum a fired bullet or a thrown baseball?

A blue ball of mass 0.350 kg traveling at 2.60 m/s to the left collides with a red ball of mass 0.350 kg that is initially at rest. After the collision, the blue ball is at rest. What is the new velocity of the red ball?

Which has more momentum a train or a car?

The momentum of an object is in the same direction as its velocity. The more momentum a moving object has, the harder it is to stop. The mass of an object affects the amount of momentum the object has. The car has more momentum because it has a greater mass.

Which has more momentum a bullet or a car?

It is the bullet traveling at high velocity that does the damage. Multiply these two numbers together and you get a bullet momentum of about 3.2 kgm/s. In contrast, modern cars have a mass of about 1500 kg. Traveling at a highway speed of 25 m/s (55 mph), a car has a momentum of about 38,000 kgm/s.

Who has more momentum?

Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

What is the momentum of the car?

Before the collision, one car had velocity v and the other zero, so the centre of mass of the system was also v/2 before the collision. The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.

Which has more kinetic energy a bullet or a baseball?

Energy generated by hitting a hockey puck, baseball, or golf ball is greater than the energy created by firing a bullet from of a gun. Many . 22 caliber bullets weigh under 3 grams and have an average velocity around 330 meters per second – this is only slightly greater than serving a tennis ball.

Does a bullet hit harder than a punch?

Very easily, the amount of force behind a bullet is simply directly equal and opposite to the recoil force exerted on the weapon firing it. Bullets often contain less kinetic energy in them than a punch does, they are simply far more efficient and precise at delivering that energy.

Is it possible for a small car and a freight truck to have equal momentum explain?

Is it possible for a small car to have the same momentum as a large truck? Yes, the small car would have to be moving with a much higher velocity, but it can have the same momentum since momentum is mass times velocity.

What is the initial momentum and stopping force of a car?

The initial momentum is 20 kg*m/s and the stopping force is 2 newtons. A plot of the x-velocity for the car and the truck looks like this: You can see that the car does indeed start with a higher velocity, but both cars stop at the same time.

What is the relationship between momentum and force in a collision?

In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton’s third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change.

What is the difference between the momentum principle and work energy?

Two things differentiate the momentum principle from the work energy. First, it is technically a vector equation because the momentum of an object depends upon its direction of movement. Second, the momentum principle depends upon the change in time (this is important).

What happens to momentum when mass is twice the speed?

A truck driving along a highway road has a large quantity of momentum. If it moves at the same speed but has twice as much mass, its momentum is ________________. Momentum is directly related to the mass of the object. So for the same speed, a doubling of mass leads to a doubling of momentum.
