question 1

Multiple Choice

An alternate statement of the uncertainty principle involves relationship between position $\Delta$ x) and momentum $\Delta$ p) uncertainties in the form . Suppose that a 40-kg runner in an imaginary world in which Planck's constant has the value 100 J • s must be located at the finish line to an accuracy of ± 0.33 m to be sure that she won the race. What would be the minimal uncertainty in the speed in that world?

• A) 0.12 m/s
• B) 0.13 m/s
• C) 0.60 m/s
• D) 1.2 m/s E 15 m/s
