# What is the kinetic energy of a 1200 kg object that is moving with a speed of 24 mm?

## What is the kinetic energy of a 1200 kg object that is moving with a speed of 24 mm?

Answer. Therefore, the kinetic energy of the 1200 kg object moving at a speed of 24 m/s is 345,600 joules.

## Which is the correct equation for calculating the kinetic energy of an object?

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.

## What is the energy of motion called?

Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle.

## What is the kinetic energy of a 45 kg object moving at 13?

What is the kinetic energy of a 45 kg object moving at 13 m/sec? 3. Solving the equation gives a kinetic energy value of 3802.5 J. Note: The unit for energy is the same as for work: the Joule (J).

## How to calculate speed?

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

## What is the formula for kinetic energy in kinetic theory?

In the kinetic energy per degree of freedom, the constant of proportionality of temperature is 1/2 times Boltzmann constant or R/2 per mole. This result is related to the equipartition theorem. Thus the kinetic energy per Kelvin of one mole of (monatomic ideal gas) is 3 [R/2] = 3R/2.

## What is the formula for electric kinetic energy?

KE(r) = ½mv2 = ½keqe2/r. The potential energy of the electron in the field of the positive proton point charge is U(r) = -qeV(r) = – keqe2/r. The total energy is the sum of the electron’s kinetic energy and its potential energy.

## What is the sum of kinetic and potential energy?

The sum of potential and kinetic energy is known as total mechanical energy.

## Who is the founder of kinetic energy?

William Thompson, who later became Lord Kelvin, is credited with introducing the concept of kinetic energy in 1849. We now associate the concept of an object’s kinetic energy with the quantity of one half of its mass multiplied by its velocity squared.

## Which state of matter has the most kinetic energy?

A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy).

## What is the kinetic energy of a body of mass 15 kg?

The kinetic energy of a body of mass 15 kg is 30j.

v = 1.28 m/s.

## What is the kinetic energy of a body of 2 kg when a force of 10 Newton acts on it for 3 second?

Solution: A force of 10 N acts on a body of 2 kg at rest for 3 seconds. The kinetic energy acquired by the body in 3 seconds will be 225 J.

## What is the kinetic energy of a 150kg object that is moving with a speed of 15m s?

What is Kinetic energy of a 150 kg object that is moving with a speed of 15 m/s. Answer: Kinetic energy is 1125 J.

## What is the momentum of a 1200 kg car with a velocity of 25 m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

## How do you calculate the kinetic energy of an object moving at a given speed?

The kinetic energy formula means: 1/2 multiplied by the mass multiplied by velocity squared.

## What is the kinetic energy of a 1500 kg car moving at 20 ms?

Therefore, the kinetic energy of the car is 300,000 J.
