We calculate the kinetic energy of a given body by the formula:

Ek = m * V ^ 2/2, where m is the given mass of the given body (m = 2.5 kg), V is the speed of the given body (V = 2 m / s).

Let’s do the calculation:

Ek = m * V ^ 2/2 = 2.5 * 2 ^ 2/2 = 5 J.

Answer: The kinetic energy of this body is 5 J.
