Answer:
more individuals are produced each generation that can survive. phenotypic variation exists among individuals and variation is heritable. those individuals with heritable trails better suited to the environment will survive.
E = m*v^2 / 2
500 = (30)*(v^2) / 2
1000 / 30 = v^2
sqrt(1000/30) = v
v = 5.774 m/s
