What is the kinetic energy of a car with a mass of 2 tons, moving at a speed of 40 m / s.

To determine the kinetic energy of a given car, we use the formula: Ek = m * V ^ 2/2, where m is the mass of a given car (m = 2 t = 2000 kg); V – speed of movement (V = 40 m / s).

Let’s make a calculation: Ek = 2000 * 40 ^ 2/2 = 1.6 * 10 ^ 6 J or 1.6 MJ.

Answer: A given vehicle has a kinetic energy of 1.6 MJ.
