Q.2 A K+ meson is created in a lab and decays into two 7 mesons in its own rest frame with its life time 12.4ns. How fast is it travellng in the laboratory if it moves a distance of 10.0m before decaying? Q.3 The visible disk of our Milky Way galaxy is about 105 light-years in diameter. A cosmic-ray proton enters the galactic plane with speed v = 0.99c. How long would it take the proton to cross teh galaxy from our point of view? What would be the corresponding time if measured from proton's frame? How wide is the galactic plane to the proton, in its direction of motion?
