## How do you calculate the speed of a car after a collision?

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i.

## How fast must a 1000 kg car be moving to have a kinetic energy of?

The car must move at 2 m/s to have a Ke of 2,000 Joules.

## How do you calculate GPE?

Gravitational potential energy changes into kinetic energy. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.

## What is momentum and how do you calculate it?

Linear momentum (momentum for brevity) is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s.

## What has more momentum a tractor trailer or a sports car traveling at the same velocity?

Which is more difficult to stop: A tractor-trailer truck barreling down the highway at 35 meters per second, or a small two-seater sports car traveling the same speed? You probably guessed that it takes more force to stop a large truck than a small car. In physics terms, we say that the truck has greater momentum.

## What do you call the change in momentum?

This change in momentum is called impulse, and it describes the quantity that we just saw: the force times the time interval it acts over. The greater the impulse, the greater the change in momentum.

## What is the momentum of a 0.2 kg steel ball that is rolling at a velocity of 3.0 m sec?

EXAMPLES Example 1: What is the momentum of a 0.2-kilogram steel ball that is rolling at a velocity of 3.0 m/sec? momentum = mx y = 0.2 kg x = 0.6 kg.

## What does the conservation of momentum state?

Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

## Is it true that the momentum of any group of objects remains the same unless outside forces act on objects?

The total momentum of any group of objects remains the same, or is conserved, unless outside forces act on the objects. “Sticky Collisions” Sometimes objects end up sticking together during a collision.

## How do you calculate accident speed?

How Do I Calculate Speed and Distance in a Car Accident Case? The formula for speed and distance is the same for a car as any other object: distance ÷ time. So if you want to calculate the speed of a car at sixty miles an hour, the math is (60 x 5280) ÷ (60 x 60) = 88 feet per second.

## What is considered a high speed car accident?

In contrast, high-speed collisions occur when a vehicle travels in excess of 30 miles per hour. These accidents often occur on highways, freeways, and other high-speed routes.

## What happens when a car hits you from the side?

A side impact accident happens when a car is hit on its side at an approximate 90-degree angle. When a side impact collision happens, the victim may file a personal injury lawsuit. Often, side impact collisions are the result of negligence.
