The force needed to lift the stone is (M G) = (5 x 9.8) = 49 newtons
Work = (force) x (distance) = (49 x 1) = 49 newton-meters = 49 joules
The amount of work done is equal to the force applied multiplied by the distance the object is raised. In this case, the work done is equal to the force F multiplied by the height of 5 meters.
It's exactly the gravitational potential energy that the stone had, relativeto the ground, before it was dropped:M G H = (9.8) x (the stone's mass) x (the height of the building) joules
The work done in lifting a 100 N box 3 meters off the ground is 300 Joules (100 N * 3 m = 300 J). Work is calculated as force multiplied by distance in the direction of the force.
An example of doing work is lifting a box from the ground to a shelf. In this scenario, work is being done against gravity to move the box vertically.
The work done on the block is 350 J, which can be used to raise the block against gravity. Work done = force x distance. So, distance raised = work done / force = 350 J / 7 N = 50 meters.
Acts of violence against companies that use sweatshops
Boycotts of major companies that profit from sweatshops.
There are a great many things in the world that are being done to save Pandas. Shirts are being sold to raise money for this purpose for example.
The bad ozone is at ground level. It is treated by afforestation.
When a stone comes out of the ground it may have different shapes, cubes, rhombic or dodecahedral. None of those shapes have the brilliance, shape or shine that you'd associate with the rings and necklaces at your local jeweler. So, rough stones are sent to a cutter who uses various tools and polishing methods to shape and smooth the stone to get the best possible aesthetics from it. When the cutter is done it has gone from being a rough to a cut stone.
When a person climbs a ladder, his muscles provide the energy (work) to raise the person's weight from the ground to the top of the ladder. When the person climbs a ladder carrying a load in addition to his body, his muscles provide the energy (work) to raise his weight from the ground to the top of the ladder, plus the additional energy (work) to raise the load from the ground to the top of the ladder. The more weight goes up the ladder, the more work is done. Of that you can be positive.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.

I assume this might be to keep any dirty ground water from running into the pool.
Yes, when they do this it is called surface mining.
