We're going to use the equation for vector magnitude:
The total distance traveled is given by:
d = AB + BC + CD + DE
The bacterium E coli is a single-celled organism that lives in the gut of healthy human and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed of 11 micometers per second. The figure shows the trajectory of an E. coli as it moves from the origin at point A to Point E.
a. Calculate the total distance traveled.
b. Calculate the magnitude of the net displacement for the entire motion.
c. What's is the bacteriums average speed for the entire trip?
d. What is the magnitude of the bacteriums average velocity for the entire trip?
