The kinetic energy of the sports car is 630 KJ.

The kinetic energy is the energy possessed by the system by virtue of its motion.

  • Also kinetic energy is equal to the net work done on the object.

KE = ΔW

  • The SI unit of the kinetic energy is joule (J).
  • The formula to calculate the kinetic energy is KE = (1/2)*m*v²

Where,

m = mass of the object

v = speed at which the object is moving

  • Kinetic energy depends on the speed squared of the object. This means that when an object's speed is doubled, its kinetic energy is quadrupled.

Mass of the car = 1400 Kg

Velocity of the car = 30 m/sec

KE = (1/2)*1400*(30)²

KE = (1/2)*1400*900

KE = 630000 J

KE = 630 KJ

The kinetic energy of a 1400 kg sports car travelling down the road with a speed of 30 m/s 630 KJ.
