A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinet
Leto [7]

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

<h3>How to calculate kinetic energy?</h3>

The kinetic energy of a moving car can be calculated using the following formula:

K.E = ½ × m × v²

Where;

  • K.E = kinetic energy
  • m = mass
  • v = velocity

K.E = ½ × 1324 × 20²

K.E = 264800J

Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
