Electron in mm and that for the bullet in m. For the electron, how is momentum related to velocity? What is the uncertainty in the velocity, based on the speed and uncertainty percentage? Be sure to express your answer in units of millimeters (mm). For the bullet, how is momentum related to velocity? What is the uncertainty in the velocity, based on the speed and uncertainty percentage? For the bullet, 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 0.400c measured with the same accuracy? (Give the lower limit for the electron in nm and that for the bullet in m). For the electron, again, you will need to use the uncertainty principle, but note now the velocity is high compared to the speed of light. So, you will need to use the relativistic definition of momentum. To find the uncertainty in velocity, treat the momentum and velocity uncertainties as differentials. This will require finding the derivative of relativistic momentum with respect to velocity.
