Answer:
The total mechanical energy of the bird is, E = 28 J
Explanation:
The total mechanical energy of the system is the sum of the potential and kinetic energy of the system.
When a bird is flying at a certain height from the ground, it posses partial potential and kinetic energy.
The total energy,
E = P.E + K.E
P.E = mgh J
K.E = ½ mv²
The total mechanical energy of the bird at any instant of time is equal to its potential and kinetic energy.
Hence, the mechanical energy of the bird is, E = 25 J
