Abird has kinetic energy of 3 j and the potential energy of 25 j what is the mechanical energy of the bird 3 j because mechanical energy is the same as kinetic energy

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

answer: electrons

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
