What is the kinetic energy of a body with a mass of 2 kg moving at a speed of 3 m / s?
| June 11, 2021 | education
To calculate the value of the kinetic energy of the specified body, we apply the formula: Ek = m * V ^ 2/2.
Variables: m is the mass of the indicated body (m = 2 kg); V – speed of movement (V = 3 m / s).
Calculation: Ek = m * V ^ 2/2 = 2 * 3 ^ 2/2 = 9 J.
Answer: The kinetic energy of the specified body is 9 J.
