To calculate the mass of a given moving body, we will use the formula: Ek = m * V ^ 2/2 and V = √ (2Ek / m).

Variables: Ek – kinetic energy of the body (Ek = 100 J); m – body weight (m = 2 kg).

Let’s calculate: V = √ (2Ek / m) = √ (2 * 100/2) = 10 m / s.

Answer: The speed of a given moving body is 10 m / s.
