Answer:

The total work done to throw a stone upward and raise to it a height of 2.5 m is done against the gravitational force. Thus, it is equal to the potential energy of the body at that height. Thus, total work done will be 6.25 J.

Answer:

The work done by the force of gravity is 6.12 Joules.

Explanation:

It is given that,

Mass of the stone, m = 250 g = 0.25 kg

It is thrown up to a height of 2.5 meters.

It is required to find the work done. It can be calculated by the force of gravity when a stone thrown up. It is called its potential energy. It is given by :

E=mgh

E = 0.25*9.8*2.5

E = 6.12 Joules

So, the work done by the force of gravity is 6.12 Joules. Hence, this is the required solution.
