# A bullet has been shot from a moving car

• Akash47
In summary, a bullet is fired from a car moving at 20 m/s with a velocity of 150 m/s. The bullet hits a wall and stops, causing a rise in temperature that can be calculated using the equations for kinetic energy and heat transfer. To find the real velocity of the bullet, the velocity of the car and the velocity of the bullet with respect to the car must be added together.

## Homework Statement

A man in a car moving with a speed ##20~ms^{-1}## shoots a bullet forward with a speed of ##150~ms^{-1}##. The bullet hits a wall and stops. Find the rise in the temperature of the bullet if its specific heat is ##500~Jkg^{-1}K^{-1}##.

## Homework Equations

##K.E=1/2~mv^2## and the amount of heat ##Q=mSΔθ##

## The Attempt at a Solution

If the real velocity of the bullet can be fined,then the problem will become very easy.I think, as the bullet was moving with the same velocity,so the velocity of the bullet with respect to the wall will be the addition of the velocity of the car and the velocity of the bullet with respect to the car.I want to know whether I am right or not.

Is right

## 1. What is the impact of a bullet being shot from a moving car?

The impact of a bullet being shot from a moving car can vary depending on the velocity and angle at which the bullet is fired. It can also be affected by external factors such as wind resistance and gravity.

## 2. Can a bullet fired from a moving car reach its intended target?

Yes, it is possible for a bullet fired from a moving car to reach its intended target. However, the accuracy and effectiveness of the shot may be affected by the speed and movement of the car.

## 3. How does the speed of the car affect the trajectory of the bullet?

The speed of the car can greatly affect the trajectory of the bullet. The faster the car is moving, the more the bullet will be affected by external factors such as wind resistance and gravity, which can alter its intended path.

## 4. What happens to the bullet after it is fired from a moving car?

After the bullet is fired from a moving car, it will continue to travel in a straight line until it is affected by external forces such as wind resistance and gravity. It will also lose velocity and energy over time, reducing its speed and impact.

## 5. Is it safe to shoot a gun from a moving car?

No, it is not safe to shoot a gun from a moving car. Not only does it increase the risk of accidents and injury to the passengers in the car, but it also poses a danger to other people and property in the surrounding area.
