An object with a mass of 2 kg is falling at a speed of 7\ m\cdot s^{-1}. What is the kinetic energy of this object?

P.-S.

The equation for kinetic energy is:

{\color[RGB]{2,112,20}{\bm{E_C = \frac{1}{2}\cdot m\cdot v^2}}}\ \to\ E_C = \frac{1}{2}\cdot 2\ kg\cdot 7^2\ m^2\cdot s^{-2} = \fbox{\color[RGB]{192,0,0}{\bf 49\ J}}
