In a research paper (Tucker and Schmidt-Koenig, 1971)*, it is demonstrated that a species of Australian parakeet expends energy according to the formula ] 22 ) 35 ( 074 . 0 [ 1 2 + - = v v E where v is the bird’s velocity (in km/h). Find a formula for the rate of change of E with respect to velocity v . 13. The growth of certain insects varies with temperature.
