At the time t= 0 a light signal is sent from the origin of frame K to the point x = 4 m, y 8 m, and z = 8 m, frame K' is coincident with frame K at the time t = t' - 0 and is moving along the x-axis of frame K in the positive direction at a speed of v=0.8c. Determine the following. (a) time (in s) at which the signal is received in frame K (b) the coordinates (in m) for the position (x, y, and z' in m) in frame K m y' = 2' a m m (c) the time (in s) it took the light signal to reach the specified point according to an observer in frame k, using the results of part (b)
