Chapter 2, Problem 51PCE
BIO Bacterial Motion Approximately 0.1% of the bacteria in an adult human’s intestines are Escherichia coli. These bacteria have been observed to move with speeds up to 15 μm/s and maximum accelerations of 166 μm/s2. Suppose an E. coli bacterium in your intestines starts at rest and accelerates at 156 μm/s2. How much (a) time and (b) distance are required for the bacterium to reach a speed of 12 μm/s?

of 4.0 m/s. Three seconds later the bicyclist hops on his bike and begins to follow the
friend with an initial speed of 10 m/s. Assume the bicyclist continues at a constant
speed of 10 m/s until he catches the friend.
a) Calculate the time it takes to catch his friend.
b) How fast is he moving when he catches his friend?
c) How far did he travel to catch his friend?
