Heisenberg Uncertainty Principle Question

  1. May 20, 2008 #1
    A measurement establishes the position of a proton with an accuracy of ±1.00 x 10 ^ -11 m. Find the uncertainty in the proton's position 1.00s later.



    DE Dt ≥ h / 4 ∏ Dx Dp ≥ h / 4 ∏



    using
    DE Dt ≥ h / 4 ∏
    DE = 5.276*10^-35 J
    where t = 1.00s

    I am stuck as I am unable to continue on

    first find delta-p, since you have delta-x

    then you find delta-E, you must know if you should use relativistic or non-relativistic kinematics.
