a stone of mass 10kg falls from the highest of 20m then calculate the work done

1 answer

To calculate the work done by the stone, we need to use the formula:

W = mgh

where W is the work done, m is the mass of the stone, g is the acceleration due to gravity (9.8 m/s^2) and h is the height from which the stone falls.

Substituting the given values, we get:

W = 10 kg x 9.8 m/s^2 x 20 m

W = 1960 J

Therefore, the work done by the stone when it falls from a height of 20 m is 1960 J.
