The work-energy theorem says that the total work done on the block is equal to the difference of its kinetic energies at points B and A. Then the total work done on the block is

Friction acts on the block to oppose its motion, so it does negative work on the block, -4.5 J.
The only other force acting on the block as it moves is the force <em>P</em>. Let
be the work done by the force <em>P</em>. Then the total work done on the block is

Answer:
Review the explanation.
Explanation:
Hydropower does not generate CO2 emissions, therefore it is not a factor in the generation of global warming. The initial investment of this type of projects in construction is large but this investment can be recovered in the future, since the system guarantees reliability in the supply of energy. It generates employment as technical and engineering personnel are needed for the operation of each of the equipment that is part of the hydroelectric plant.
As for the defects, is that most hydropower should be located near rivers, therefore to access the construction of this project must cut trees and remove animals from their natural habitat.
