A turtle ambles leisurely, as turtles tend to do, when it moves from a location with position vector ????1,x=1.33 m and ????1,y=
−2.89 m in a lettuce garden to another location, with position vector ????2,x=3.07 m and ????2,y=−4.33 m, where the lettuce appears to be tastier (but really is not; this turtle cannot see very well). The excursion takes 327 s to complete. What are the components and the magnitude of the turtle's average velocity in meters per second?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages).
