# What is the kinetic energy of a 25 kg object moving at a velocity of 5 m/s?

## Question:

What is the kinetic energy of a 25 kg object moving at a velocity of 5 m/s?

## Kinetic energy

Kinetic energy is the kind of mechanical energy that a body opposes when it is in motion. The mathematical expression for the kinetic energy is the half multiplication of mass and speed square; its unit is the joule.

## Answer and Explanation:

**Given data**

- The mass of the object is:

m = 25\,\,{\rm{kg}
