No, because the collision only affect a tiny amount of the surface of the train. Depending on the relative mass and speed of the molecules of the fly and train, the initial molecular collisions could result in a net “backwards” movement of both.

## How do you solve the train car problem in physics?

## What is the momentum of a train?

The average train would have a momentum between 143,200 ? 179,000 ton*m/s as it travels.

## How do you find the acceleration of a train?

## Why is a car moving at 30 m/s harder to stop than a baseball moving at 30 m s?

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. For example, you can catch a baseball moving at 20 m/s, but you cannot stop a car moving at the same speed. The car has more momentum because it has a greater mass.

## What has more momentum a car or a train?

Although the train and the car have the same velocity, the train has more mass than the car so the train has greater momentum.

## What happens to the momentum when a car moves twice as fast as the other car?

A moving car has momentum. If it moves twice as fast, its momentum is twice as much.

## Can a bee stop a train?

A bee traveling near the speed of light would not stop the train either. It would, however, both stop and reverse direction of many small pieces of the train!

## What happens to a fly on a train?

@Yan – if the air is moving with the train, the fly will get dragged with it due to air resistance.

## Can trains fly?

## How much time does it take the train to stop?

Trains have the right-of-way because they cannot quickly stop for a motorist at crossings or for trespassers on the tracks. The average freight train, traveling at 55 MPH, takes anywhere from 1 to 1½ miles to stop. Traveling at the same speed, the average automobile can stop in only 200 feet.

## What is the position of the car at the end of the 10 seconds?

Answer: Position of the car at the end of 10 seconds is 400 meters away from the starting point.

## What is the velocity of the jumper at the end of 1.5 s?

Answer and Explanation: Velocity of jumper at the end is 14.7 m/s.

## Is it possible for a bullet to have the same momentum as a truck?

ANSWER: Yes, for a bullet to have the same momentum as a truck, it must have a higher velocity because the two masses are not the same.

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

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. If the momentum of an object changes and its mass remains constant, it is accelerating (or decelerating), there is a force acting on it, its velocity is changing.

## Which has more momentum a 1000.0 kg car moving 1.00 m/s or a 70.0 kg person sprinting at 8.00 m s?

The momentum is the product of the mass and speed. Hence, the car has more momentum.

## When these two train coaches of different masses collide and couple what will be their resultant velocity?

We can apply the concept of conservation of momentum. Velocity of the combined masses be v. Therefore, the speed of combined masses after the collision will be 1m/s.

## Why is it harder to stop a train than a car even when the car is moving faster?

Because the Mass of train is more than that of the car, when they are moving at the same speed the force required to stop the train is much more than compared to that of the car.

## Is it possible for a small car and a freight truck to equal momenta?

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.

## When a car comes to a sudden stop the passengers lurch forward this is an example of?

As a more familiar example of inertia, think about riding in a car. You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward.

## What happens to the total momentum in a collision?

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.

## What happens if mass and velocity are doubled?

Thus Kinetic energy is directly proportional to mass and velocity. Since mass is directly proportional to K.E and K.E is directly proportional to the square of velocity the kinetic energy becomes eight times.

## Why do bees keep coming back to the same place?

One of the biggest reasons why honey bees return is because of the remnants of a previous infestation. Honeycomb contains odors that will attract other bees.

## What happens when the queen bee dies?

Lastly, when a honey bee queen suddenly dies, an urgent and unplanned supersedure occurs. Worker honey bees identify several larvae within the proper age range and begin to condition these larvae to become queens.

## Is it possible to train bees?

Honey bees are renowned for their ability to perform complicated tasks and learn complex associations. Their ability to be trained quickly both in indoor laboratory settings and in outdoor field experiments makes them valuable research subjects.
