(a) an electron and a 0.0440-kilogram bullet each have a velocity of magnitude 510m/s, accurate to within 0.0100%. within what lower limit could we determine the position of each object along the direction of the velocity? (b) what if? within what lower limit could we determine the position of each object along the direction of the velocity if the electron and the bullet were both relativistic, traveling at 0.300c measured with the same accuracy? (give the lower limit for the electron in nm and that for the bullet in m.)
