A bird has a kinetic energy of 3 J and a potential energy of 25 J. What is the mechanical energy of the bird?
O 33, because mechanical energy is the same as kinetic energy
O 223, because mechanical energy is the difference of the potential energy and kinetic energy
O 25 J, because mechanical energy is the same as potential energy
O 28 J, because mechanical energy is the sum of the potential energy and kinetic energy
