Final answer:
The mechanical energy associated with position A is both kinetic and potential energy.
Step-by-step explanation:
The mechanical energy associated with position A is in the form of both kinetic and potential energy. Mechanical energy is the sum of kinetic energy and potential energy. Kinetic energy is the energy associated with the motion of an object, while potential energy is the energy stored in an object due to its position or condition. In the case of position A, it is likely that there is both motion and a position or condition that stores energy, so both kinetic and potential energy are present.
