Unformatted text preview: Massachusetts Institute of Technology Department of Physics Physics 8.022 - Fall 2002 Assignment #7 Spacetime in Special Relativity Forces, Momenta, Fields, Energies in Special Relativity Fields of Moving Charges Reading Purcell: Chapter 5 and Appendix I (pages 451-458), handouts I and II (there is a second one posted!) on Special Relativity by Prof. Fisher. Problem Set #7 Work on all problems. Not all problems receive equal points. Total points for this set is 100. z (15 points)  Transforming velocities. A bullet is fired with velocity in the x ' y ' plane of a moving frame S ' and at an angle with respect to x '. Frame S ' moves with velocity v with respect to the laboratory frame S along the x axis. Find the angle the velocity vector of the bullet makes with the x axis of the laboratory frame. What if the bullet is a photon (light)? z (20 points)  ``Traveling circus beats the speed of light!'' A circus company advertises its arrival in Cambridge, Massachusetts with big headlines in local...
