Determine the impulse of a translationally moving body weighing 1 kg, the kinetic energy of which is 2 J.

To find the momentum of a body, knowing its mass, we need to find its speed. Since we know its kinetic energy, we can find its speed. The form of the kinetic energy of the body has the form Wк = (m * V ^ 2) / 2. Let’s transform the expression and find its speed: V = sqrt ((2 * Wk) / m) = 2 m / s. We can find the momentum of the body by the formula p = m * V = 1 * 2 = 2 kg * (m / s ^ 2).
