The kinetic energy of the moving sled with the given value of mass and velocity is 7.84 × 10³ Joules.
What is Kinetic Energy?
Kinetic energy is simply a form of energy a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given the data in the question;
- Mass of the sled m = 20kg
- Velocity of the sled V = 28.0m/s
- Kinetic energy of the train K = ?
To determine the kinetic energy of the sled, we substitute our given values into the above expression.
K = (1/2)mv²
K = (1/2) × 20kg × (28.0m/s)²
K = 0.5 × 20kg × 784m²/s²
K = 7840kgm²/s²
K = 7.84 × 10³J
Therefore, the kinetic energy of the moving sled with the given value of mass and velocity is 7.84 × 10³ Joules.
