Uniform Acceleration in Special Relativity A particle moves from rest at the origin of a frame A along the positive x-axis with constant acceleration ? (as measured in an instantaneous rest frame). By integrating the expression for the acceleration measured in frame A in the lectures, we showed that the particle velocity ux in that frame has the form at Ux = V1+ a2t2 (2) (a) Show that the motion of the particle in the rest frame A is given by -1+ V1+ a2t2 x= a (3) [3 marks] (b) A standard clock carried along with the particle is set to read zero at the beginning of the motion and reads 7 at time t in A. By directly integrating the proper time over the particle trajectory, prove that at = sinh aT [4 marks] (c) Show that if t2 < a-2 (very much less than), then, during an elapsed time t in the inertial system, the particle clock will record approximately the time Hint: compute the Taylor expansion for T = a-1 sinh-1 at for small t [3 marks] (d) For a = 3g (where g = 9.81 m s-2 = 9.81 10-8 c s-1), find the difference in recorded time by the particle clock and one in the inertial frame (i) after 1 hour, (ii) after 10 days [2 marks]
