How do I graph the position for this velocity-time graph?

  1. Nov 16, 2015 #1
    1. The problem statement, all variables and given/known data
    Between t = 0 seconds to t = 2 seconds the velocity is 3 m/s ihat. Between t = 2 seconds and t = 6 seconds the velocity is -2 m/s ihat. I need to know what the position is at each second.

    2. Relevant equations
    Position = velocity * dt

    3. The attempt at a solution
    I know that the position for the first 2 seconds is a linear line with a slope of 3 m/s. But I'm not sure about the position for t = 2 seconds through t = 6 seconds.

    The velocity is the slope of the line.
    You know the position at t=2s, and you know the slope... so use a ruler.
    If you get confused... the velocity is the amount the position changes by in one second.
    Between 2 and 3 seconds, what is the velocity?

    Your equation is incorrect: if displacement is s, then ds = v.dt
    For constant acceleration a this turns into the suvat equations.
