Respuesta :
Kinetic energy = 1/2 * mass * velocity (squared)
= 1/2 * 50 * 4
= 1/2 * 200
= 100 J
= 1/2 * 50 * 4
= 1/2 * 200
= 100 J
The kinetic energy of the moving object with the given value of mass and velocity is 100 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 train m = 50kg
- Velocity of the train V = 2m/s
- Kinetic energy of the train K = ?
To determine the kinetic energy of the object, we substitute our given values into the above expression.
K = (1/2)mv²
K = (1/2) × 50kg × (2m/s)²
K = 0.5 × 50kg × 4m²/s²
K = 100kgm²/s²
K = 100J
Therefore, the kinetic energy of the moving object with the given value of mass and velocity is 100 Joules.
