A cyclist stops at a stop sign. After he checks the intersection, he begins pedaling again. He reaches a velocity of six meters per second in three seconds. What's the cyclist's acceleration? HELP ME PLEASE

what is it? i need to write it so i can talk u through this,okay?

What do you mean the formula? Oh gosh I am not good at this!

That is all that is there

can you use velocity = intial velocity + accel x time? do you think you have all the data required?
anonymous
  • anonymous
I have the initial velocity. That is 0. The velocity now is 2 m/s2 (That is squared. I do not know what direction the person is going) Time is 3 seconds I need the acceleration
anonymous
  • anonymous
v=u+at
kl0723
  • kl0723
since the cyclist stops and the starts to pedal again means that he starts from rest, then initial velocity is zero, you're given time and final velocity or max velocity in this case
anonymous
  • anonymous
u=0 v=2m/s t=3 s a=?
anonymous
  • anonymous
Yes?
kl0723
  • kl0723
from the equation can you solve for Acceleration and then plug in your data?
shreenithaa
  • shreenithaa
well, first of all, the formula is velocity equals distance divided by time acceleration is velocity final minus velocity intial over time final minus time intitial
shreenithaa
  • shreenithaa
use this info to calculate ur math
anonymous
  • anonymous
so it is 6 - 0 / and 3 - 0? so the acceleration is 2?
shreenithaa
  • shreenithaa
velocity is 2 but u need final velocity and the starting velocity and final time and beginning time in order to get the acceleration we know that final time is 3 seconds
anonymous
  • anonymous
I have the final velocity though. It is 2 m/s (Squared) the direction is not given. What I gave is what I have
shreenithaa
  • shreenithaa
what if the starting time is 0 so now we need the initial velocity
anonymous
  • anonymous
initial velocity is 0 m/s (Squared) since they are at a stop sign
shreenithaa
  • shreenithaa
since the starting is 0 so the velocity must be 0 right?
anonymous
  • anonymous
Yes
shreenithaa
  • shreenithaa
so ur answer is acceleration is 2
anonymous
  • anonymous
That is it?
shreenithaa
  • shreenithaa
u were right the whole time sorry for the confusion
anonymous
  • anonymous
The answer is just 2?
shreenithaa
  • shreenithaa
no it has to have the units
anonymous
  • anonymous
What are said units? Like are the from the problem, or?

2=0+a*3 a=2/3 m/s^2
anonymous
  • anonymous
I er, have no idea what that means if we are being honest here
shreenithaa
  • shreenithaa
wow same grad right!!! i moved to virginia where i had honors science so i learned this i was in cali for most of the time dont worry i am dumb in many places,but math and science are my specialty u'll find urs
anonymous
  • anonymous
But thanks. Really!|dw:1442535044863:dw|

  • anonymous
\[v=u+at\] \[2=0+a*3\] 3a=2 \[a=\frac{ 2 }{ 3 }m/s^2\]

sorry ,i miss read ,it is 6 m/s i thought 2 m/s you are correct 6=0+3a a=2 m/s^2
