At what distance from the table will a metal ball fall to the floor if it rolls on the table at a speed of 7.2

At what distance from the table will a metal ball fall to the floor if it rolls on the table at a speed of 7.2 km / h, and the table height is 80 cm?

The flight range of the metal ball is calculated by the formula:
l = V0 * √ (2h / g), where V0 is the speed of the ball when moving on the table (V0 = 7.2 km / h = 7.2 * 1000/3600 = 2 m / s), h is the height of the table (h = 80 cm = 0.8 m), g is the acceleration of gravity (we take g = 10 m / s²).
Let’s calculate the range of the balloon:
l = V0 * √ (2h / g) = 2 * √ (2 * 0.8 / 10) = 2 * √ (0.16) = 2 * 0.4 = 0.8 m.
Answer: The flight range of the metal ball will be 0.8 m.
