(10 points) A pair of friends, B1 and B2, bid good bye to each other. B1 is the friend that is in a rocket frame while B2 is the one who was left. As B2 bid good bye, he fired a fireworks. As it exploded, B2 observed the explosion at (4.00 [m], 7.00 [m]) 37 40 while B1 observed the explosion at [m]). What is velocity of the rocket 7 B1 is in? 9 (10 points) The tauon particle or tau particle (T), which is a relative of the electron particle (e-) and the muon particle (u), has an average lifetime of 8.718 x 10-5 [m] when it is at rest. If it moved across 15 [m] of space over 16 [m] of time according to an observer, what would be the observer's measurement of the tauon particle's average lifetime? (10 points) After attending your Physics 73 class, you saw your crush in a Physics 71.1 class. In the presence of your crush, you were stunned. You saw your crush holding a stick. For you, it seems be a six-inch stick. He was walking towards you at a rate of 0.3 when you saw it. It is as if your crush is measuring something between the two of you. What is the real length or the proper length of the stick your crush is holding? (10 points) A pair of friends, B1 and B2, bid good bye to each other.
