What is the kinetic energy of a 28 kg body moving on a horizontal surface at a speed of 36 km / h?

Let’s write the formula for kinetic energy: Ek = (mU ^ 2) / 2. Converting the data into the SI system (36km / h = 10m / s), we substitute the data into the formula and get: Ek = (28 * 10 ^ 2) / 2 = 1400J.
