The formula to calculate the Velocity (V) from Height (H) is:
\[ V = \sqrt{\frac{2H}{a}} \times a \]
Where:
Let's say the height (\( H \)) is 20 meters and the acceleration due to gravity (\( a \)) is 9.8 m/s². Using the formula:
\[ V = \sqrt{\frac{2 \times 20}{9.8}} \times 9.8 \approx 19.8 \text{ m/s} \]
So, the Velocity (\( V \)) is approximately 19.8 m/s.
Velocity is the speed of something in a given direction. In this context, it refers to the speed at which an object falls from a certain height under the influence of gravity.
