Question

The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans 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 20?m/s . The figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC.(Figure 1

Please Answer All Questions Thank You (and both answers should be in micrometers per second squared)

A) For the segment

The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans 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 20?m/s . The figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC.(Figure 1) For the segment DE in the bacterium's trajectory, calculate the x component of its velocity For the segment DE in the bacterium's trajectory, calculate the y component of its velocity

Explanation / Answer

1) what is the speed unit??

it appears as ?m/s .. i have taken it as micro m/s

s = 50 root(2)

t = 50 root(2) / 20

= 2.5 root(2)

x = -50 micro m

vx = -50 / 2.5 root(2)

= -10 root(2) micro m/s

2) y = -50 micro m

vy = -50 / 2.5 root(2)

= -10 root(2) micro m/ s
