a bird 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
