Question
An observer sees a system moving past her that consists of a massoscillating on the end of a spring and measures the periodT of the oscillations. A second observer, who is movingwith the mass-spring system, also measures its period. What periodwill the second observer find the period to be? 1 equal to or less than T dependingon whether the system is approaching or receding from the firstobserverequal to, greater than, or less thanT depending on whether the system is approaching orreceding from the first observer
