Heisenberg Uncertainty Principle question

    [SOLVED] Heisenberg Uncertainty Principle question

    Suppose that the x-compenent of the velocity of a 3.0 x 10^-4 kg mass is measured to an accuracy of plus or minus 10^-6 m/s. What then is the limit of the accuracy with which we can locate the particle along the x-axis?

    Any help on where to start here would be helpful, thanks.

    how is momenta related to mass and velocity? Thats all you have to do. And you should first consider if you want to use relativistic or newtonian expression for the momenta.

    You titled this "Heisenberg Uncertainty Principle". Do you know the formula that gives that principle?
