Answer: The correct answer is mechanical energy.
Explanation:
Mechanical energy is the sum of the both potential and kinetic energies.
M.E = P.E + K.E
Potential energy is due to the position of the object.
Kinetic energy is due to the motion of the object.
When the barbell is lifted then it will have potential energy with small amount of kinetic energy.
When the shot put is thrown then there will be both potential energy and the kinetic energy.
Therefore, the mechanical energy is present in a barbell being lifted or a shot-put being thrown.
