11 12 13 14 1 5 6117 8 10 12 13 14 15 Superman is flying towards a space station at a relative speed of 0.4c with respect to the space station. When superman observes himself to be 0.05 ly from the station, an object passes him heading towards the station at 0.6c relative to superman. (a) In the inertial reference frame of the space station, how many days is it to the nearest day) before the space object collides with the space station? (b) Draw a Minkowski diagram that includes the spacetime axes (x, ct) for superman's reference frame, the spacetime axes for the space station, and the trajectory of the space object. Please specify the angles between the different lines in the diagram. (c) What is the spacetime interval s between the event of the object passing superman and the event where the object collides with the space station? Is it possible for these events to be simultaneous in any inertial reference frame? Justify your answer in one or two sentences at most. (d) When the space object arrives at the space station observers on the space station determine that the kinetic energy of the object is 26 GeV. What is the rest mass of the object? Hence, identify what the object might be

a,b,c and d

alonmally 09 it takes 5 days are 16 hourss to pass and yes it is possible, becourse these dients are kimultaneous. 10 d as 31 12 it u 2.6 Gen. rest Mass Mo = 9.1810 hence it is an electron kg 01 3 4/4
