Kinetic energy of an object (3440)
Sábado 2 de enero de 2016, por
An object with a mass of 2 kg is falling at a speed of 
. What is the kinetic energy of this object?
The equation for kinetic energy is:
![{\color[RGB]{2,112,20}{\bm{E_k = \frac{1}{2}\cdot m\cdot v^2}}}\ \to\ E_k = \frac{1}{2}\cdot 2\ kg\cdot 7^2\ m^2\cdot s^{-2} = \fbox{\color[RGB]{192,0,0}{\bf 49\ J}}](local/cache-vignettes/L525xH46/6595944ccfbf1b4cf18f63abe46e69db-d203b.png?1742681072 "{\color[RGB]{2,112,20}{\bm{E_k = \frac{1}{2}\cdot m\cdot v^2}}}\ \to\ E_k = \frac{1}{2}\cdot 2\ kg\cdot 7^2\ m^2\cdot s^{-2} = \fbox{\color[RGB]{192,0,0}{\bf 49\ J}}"){kind=small}
