niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle

competitive exclusion principle

The competitive exclusion principle suggests that no two species can occupy the same ecological niche (functional role an organism performs in an ecosystem like type of food, and habitat chosen for living) in the ecosystem, the one which is stronger and superior over the other is likely to derive the resources and exhibit better chances of survival.  

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
