Answer to Question #114862 in Physics for Pol

Question #114862

v_f= √(2 (-9.8 m/s^2 )(-25m))

Expert's answer

This is an equation that can be obtained from the law of conservation of energy: potential energy transforms into kinetic energy.

"mgh=\\frac{1}{2}mv^2,\\\\\nv=\\sqrt{2gh}=v_f= \\sqrt{2 \\cdot9.8 \\cdot25}=22\\text{ m\/s}."
