  1. Sep 11, 2012 #1
    1. The problem statement, all variables and given/known data
    In the picture.

    2. Relevant equations
    I guess λ=cv? I'm not sure on this one.

    3. The attempt at a solution
    I don't know how the velocity and the displacement are related in this exercise. However, i do recall the graphs of displacement, velocity and acceleration in SMH.
