Chapter S4, Problem 54EAP

Be sure to show all calculations clearly and state your final answers in complete sentences.

54. An Eiectron's Quantun Uncertainly. Yon are conducting an experiment in which you can measure the location of individual electron collisions to within 10-10 m. What is the theoretical limit to which you can simultaneously measure the momentum of those collisions? What is the uncertainty in the election's speed? (The electron has a rest mass of $\text{9}.\text{1}\times \text{1}{0}^{-\text{31}}$ kg.)
