N:43) Two boys, Matthew and Joseph are 10 year old twins. Matthew takes a trip into outer space in a new experimental rocket which moves at 0.8c relative to Earth. The rocket can only hold one person, so Joseph must stay on earth. According to Joseph, Matthew leaves for 20 years; but, when Matthew returns, Joseph is 30 years old. How old is Mo when he returns? A) 12 years B) 28 years C) 30 years D) 22 years
3 A spaceship (A) is moving at speed c/2 with respect to another spaceship (B). Observers in A and B set their clocks so that an event at (x, y, z, t) of a photon arriving has coordinates (0, 0, 0, 0) in A and also (0, 0, 0, 0) in B. A second photon arrives at (x = 1.00 m, 0, 0, 0 s) in the frame of ship A. (a) Find the coordinates and time of the second photon arriving as seen by an observer in frame B. (b) In which frame are the two events simultaneous and in which frame are they are not simultaneous
