# What is the kinetic energy of a 2000 kg car that is traveling 10 m s?

## What is the kinetic energy of a 2000 kg car that is traveling 10 m s?

The kinetic energy of a 2000 kg car that is travelling at 10 m/s is equal to 10⁵ Joules. Explanation: Kinetic energy is the form of energy that is present in a body due to its motion.

## What is the momentum of a 2000 kg car that is moving at 20 m s?

. The momentum of a 2000 kilogram car traveling at 20 meters per second is: a. 0 kg•m/sec.

How do you find the kinetic energy of a moving car?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

### What is the kinetic energy of a 1000 kg car?

Answer: The answer will be 1.25 × 10^6 J.

### What is the kinetic energy formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

How is the kinetic energy formula derived?

Kinetic energy is a simple concept with a simple equation that is simple to derive. Start from the work-energy theorem, then add in Newton’s second law of motion. ∆K = W = F∆s = ma∆s. Take the the appropriate equation from kinematics and rearrange it a bit.

## What is the momentum of a 2000 kg truck that moves at 10 m s?

Momentum before the collision is p=mv=2000⋅10=20,000 kgms−1 .

## What energy is a moving car?

kinetic energy
A moving car possesses mechanical energy due to its motion (kinetic energy). A moving baseball possesses mechanical energy due to both its high speed (kinetic energy) and its vertical position above the ground (gravitational potential energy).

What is the kinetic energy of a 1000 kg car moving at 2 m s?

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

### What is the kinetic energy of a car that has a mass of 1000 kg and is moving at a speed of 30 ms?

Units: Joules (J) Page 16 Example #2: What is the Kinetic Energy of a 1,000 kg car moving at 30 m/s? KE = 450,000 J Page 17 Example #3: What is the Kinetic Energy of a 20,000 kg freight car moving at 25 m/s?

### What is the kinetic energy of a 5 kg object moving at 7 m s?

The equation for kinetic energy is ½mv2, where m is your mass and v is your velocity. So for the given information, we have KE = ½(5 kg)(72) =122.5 Joules.

What do you mean by kinetic energy?

motion
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.

## How to calculate the kinetic energy of a vehicle?

To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.

## What is the kinetic energy of 10 kg?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

How is kinetic energy related to mass and velocity?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2 .

### How to calculate the kinetic energy of a ball?

Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J. What is the velocity of the ball? First we convert 500 grams to 0.5 kg and then replace in the formula: v = √ (2 · 500 / 0.5) = 44.7214 m/s or 146.7236 feet per second.
