4. a)The speed of an electron is measured to within an uncertainty of 2.0x104 m/s. What is
the size of the smallest region of space in which the electron could be confined?
b)The Σ∗particle has a rest energy of 1385 MeV and a lifetime of 2.0x10-23 s. What would
be a typical range of outcomes of measurements of the Σ∗ rest energy?

A proton and a bullet each move with a speed 324 m/s, measured with an uncertainty of .01%. If measurements of their respective positions are made simultaneous with the speed measurements, what is the minimum uncertainty in the position measurement for the proton in units of microns and 3 significant figures? Take ?(x)*?(p) = h/(2?). The proton mass is 938 MeV/c2. You do NOT need to specify the units for this question
