Abird has a kinetic energy of 3 j and a potential energy of 25 j. what is the mechanical energy of the bird?
3 j, because mechanical energy is the same as kinetic energy
22 j, because mechanical energy is the difference of the potential energy and kinetic energy
25 j, because mechanical energy is the same as potential energy
28 j, because mechanical energy is the sum of the potential energy and kinetic energy

28 J

Explanation:

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.

In physics, mechanical energy (Emech) is the energy associated with the motion and position of an object usually in some force field.

Therefore:

ME = KE + PE = 25 + 3 = 28 J

i think the answer is tomato juice? not entirely sure though
