Uncertainty in proton position after 1.00s using Heisenberg's principle

[gaussrifile]

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.
