In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5190 km away, and released. it found its way back to its nest 15.0 days after release. if we place the origin in the nest and extend the +x-axis to the release point, what was the bird's average velocity for the return flight?

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
