Question:
Observer O detects a sound pulse emitted at event A O observes the pulse to be reflected back in the opposite direction by a rigid barrier at event B The pulse is detected again at event C The spacetime coordinates of the events according to O are:
A: xA tA
B: xBm tB and
C: xC tC tB
In the following, three decimal places are sufficient,
a If the pulse travels at a constant speed ms according to O what is tB Why?
b Observer O travels along the common x x direction with xA at tA The velocity of O relative to O is ms What are xB tB and xC tC Why?
c What is the velocity of the pulse between A and B and between B and C according to O Why?
