Answer:
Its mechanical energy is the same.
Explanation:
If forces are only conservative, the mechanical energy will be the same.
It can be different if energy get transformed in another kind of energy like elastic energy for example, although the amount of energy is always the same.
If we just have mechanical energy not geting transformed we have:
Em=K+U
Em: Mechanical energy
K: Kinetic energý
U: Potential energy
Then if Kinetic energy decreases 10J, Potential energy will grow up 10J to keep the same amount of mechanical energy.
In this exercise we have to use the knowledge of mechanical energy to describe what happens with this energy, like this:
If forces are only conservative, the mechanical energy will be the same.
Mechanical energy is a scalar quantity measured in joules. It corresponds to the result of the sum of the kinetic energy and the potential energy of a system. In conservative systems, that is, those that do not present friction or drag forces, the total mechanical energy is conserved.
In this way, we can described as:
