Uncertainty particle function evolves over time

1. Homework Statement

The position of a proton is measured with an accuracy of [tex]\Delta[/tex]x = 10^-11 m
Calculate [tex]\Delta[/tex]x one second later. Assume v << c.

2. Homework Equations

Heisenbergs uncertainty principle perhaps.

3. The Attempt at a Solution

I assume this requires knowledge about how the particle function evolves over time, but because the function is unknown in this case, its random how it evolves...

Thought a bit more about it. If i calculate the uncertainty in momentum by using heisenbergs uncertainty principle. Then multiply it by t and divide by m, to calculate [tex]\Delta[/tex]x a second after. Does this sound right?

Add that answer to Delta x.
