a falling stone a 10m/s*2

To determine the distance covered by a falling stone, we need to use the equation of motion for an object in free fall:

s = 0.5 * g * t^2

In this equation:
- s represents the distance covered by the falling stone.
- g is the acceleration due to gravity, which is approximately equal to 9.8 m/s^2 on Earth.
- t is the time taken for the stone to fall.

Given that the acceleration due to gravity is 10 m/s^2, we can substitute this value into the equation:
s = 0.5 * 10 * t^2

However, we are missing the time (t) it takes for the stone to fall. If we have this information, we can calculate the distance covered.
