A. Average velocity:
Net displacement is from O to E
Net displacement = 44.7 μm
The bacterium E. coli is a single-cell organism that lives in the gut of healthy animals, including humans. When grown in a uniform medium in the laboratory, these bacteria swim along zigzag paths at a constant speed of 25 μm/s. The following figure shows the trajectory of an E. coli as it moves from point A to point E.
What is the magnitude of the bacterium's average velocity for the entire trip?
Express your answer to two significant figures and include the appropriate units.
What is the direction of the bacterium's average velocity for the entire trip?
Express your answer using two significant figures.
