Question #161650

You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high. How long does is take the stone to reach the bottom of the cliff?

Expert's answer

"y=\\dfrac{1}{2}gt^2,""t=\\sqrt{\\dfrac{2y}{g}}=\\sqrt{\\dfrac{2\\cdot78.4\\ m}{9.8\\ \\dfrac{m}{s^2}}}=4.0\\ s."
