Find the distance

  • Thread starter farhan769
  • Start date
1. The problem statement, all variables and given/known data
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 and maximum accelerations of 166 . Suppose an E. coli bacterium in your intestines starts at rest and accelerates at 151 .
How much distance is required for the bacterium to reach a speed of 12 ?

2. Relevant equations
d=vt
t=v/a
v^2=v0^2+2ax


3. The attempt at a solution
i used v^2=v0^2+2ax
so v0 is 0 (i thiink)
12^2=2(151)x
x=.48
is this correct??
