A passenger car with a mass of m = 800 kg moves at a speed, the modulus of which is v = 20 m / s.

A passenger car with a mass of m = 800 kg moves at a speed, the modulus of which is v = 20 m / s. Determine the kinetic energy of the vehicle.

The kinetic energy of a given car can be determined by the formula: Ek = 0.5 * m * V ^ 2, where m is the mass of a car (800 kg); V – vehicle speed module (20 m / s).

Calculation: Ek = 0.5 * 800 * 20 ^ 2 = 160,000 (160 * 10 ^ 3 J or 160 kJ).

Answer: This passenger car has a kinetic energy of 160 kJ.
