5. An electron ( me = 9.11 × 10−31 kg ) and a bullet ( m = 0.02 kg) each have a velocity of magnitude 500 m/s, with a precision within 0.01%. In what limits is it possible to determine the position of objects along the velocity direction?What can you conclude from comparing your results for the electron and for thebullet?

In a lab a scientist tries to measure the location and speed of an electron.  The position measurements are found to have an uncertainty of 5.01 x 10-11 m (this is 0.0501 nm).  What is the smallest possible uncertainty in velocity?  An electron has a mass of 9.11 x 10-31 kg and Planck's constant is 6.63 x 10-34 J*s
